Bad Data Service, I am writing to make a formal complaint about the extremely slow internet service

Bad Data Service,

I am writing to make a formal complaint about the extremely slow internet service on my SIM card. The connection is so poor that I cannot even watch basic videos on Facebook or YouTube. This situation has caused me significant inconvenience in my daily use.

When I contacted your colleague about this problem, I was told that I must either pay for six months or wait until the binding period ends. I find this response unacceptable. I am paying for a service that I am not able to use properly.

Your advertisements claim to provide one of the best networks, but my experience has been the opposite. The network quality I receive is very poor, and it does not meet reasonable service expectations.

I request that you investigate this issue and provide a proper solution as soon as possible. If the service cannot be improved, I expect a fair resolution, including the possibility of terminating the contract without additional charges.

Sincerely,

If I could give it 0 stars I would

If I could give it 0 stars I would. Absolute terrible customer service. They kept on taking money from my account months after I unsubscribed. Charging me 2000 dkk for a router I never recieved, and said that I used 300gbs of data on a plan I never wanted which only has 5gbs of data. The worst mobile company in the world.
