Supersonice has the worst customer service , they have a bot chatting to you on WhatsApp referring you to their website where you dont even see much information on the dashboard.

Upon applying for the order I checked coverage in my area after a couple of days I called their call center I was advised then only that there is no coverage in my area. I had to call eversince then there was no communication from them.

I canceled the order on my end and obviously thought they'd cancel the order on their end because we can't proceed with the service. I have sent 2 emails, logged a ticket and multiple phone calls later. Not really getting help from them this order still shows pending on their side.


There is absolutely no customer service here. Seems like whoever is in charge of each process does not see their processes through. Plainly not doing their job. This was my first encounter with Supersonic and definitely my last.

The ticket I logged is the same ticket number the lady gave me whilst she said she is logging a call. Its just so astonishing. I am in customer service type of job and this? Is really bad for their business.

I do not recommend anyone to make use of their services

Disappointing billing practices

I was using a month-to-month fibre service, and my account was suspended and then reactivated without my consent, leading to termination by the provider. They later demanded payment that included several months of fees after suspension, violating contract principles. The lack of transparency in billing is concerning, and customer support has been unhelpful. My reasonable attempts to resolve the account were ignored. I cannot recommend this service due to poor practices and disregard for consumer rights.

Service is worse than non-existent

As a long-time client, I reported an issue with WiFi not reaching certain rooms in my home. I followed up multiple times and made several calls, only to be informed that they do not provide that service! This has been a complete waste of my time and money; I strongly advise against using them.

If I could give zero stars, I would

If I could rate them with zero stars, I absolutely would. I've been without internet for four days. I submitted three support tickets with no response. Every time I call, I get cut off because my ID number is said to be invalid. My account dashboard shows everything is fine, but it is not. There seems to be no way to resolve this. I strongly advise against using this service; their customer support is terrible!

Kudos to the representative!

I want to acknowledge the representative who took full ownership of my situation from start to finish, where others might have dismissed me. Thank you for your proactive approach in keeping me connected!

Zero stars would be more appropriate

If I could rate them with zero stars, I absolutely would. This has been the worst experience I've ever had. We've been without internet for a week due to a billing issue. Our service was cut off last week, and despite numerous emails and calls, our ticket remains unresolved. We've sent proof of payment multiple times without any acknowledgment, and both my and my husband's numbers have been blocked, preventing any follow-up. It feels like theft to take money without providing a service. We can't even cancel despite submitting a cancellation request; there's been no acknowledgment at all. A new provider informed us that they need to release the line before we can switch. How can we do that when we can't get a response?

No stars to give

No stars at all. Their service is atrocious. Cancelling your contract with them is even worse. I have a strong dislike for this service and wouldn't recommend it to anyone.

Thank you for the assistance!

I'd like to express my gratitude for the representative who helped us get connected. We had spoken to various agents who couldn't assist us, but this representative made a significant difference. We were even considering cancellation, but thanks to her excellent service, we decided to stay. Truly appreciated!

Disappointed with the service

I've been a loyal customer for years, and when I was directed to this service, I overlooked the bad reviews. Initially, I thought everything was fine, but then issues arose with billing. Despite reaching out multiple times, I received no satisfactory response regarding a refund for a double payment. The billing practices are confusing and untrustworthy, and the customer support is lacking. I decided to cancel my service, but the process has been frustrating and unclear. I would not recommend this service.

Unacceptable service – 9 days without internet!

I've had an incredibly frustrating experience with the fibre service. My internet has been down for over 8 days, and despite submitting multiple requests and calling daily, I've received no updates. I've spoken to several representatives, but after 9 days, my issue remains unresolved. The lack of urgency and follow-up is alarming. This level of service is unacceptable for a company that provides essential connectivity. I strongly advise against using this service if reliability is a priority.
