Worst product experience. I used one bottle and it was completely ineffective—it did not resolve the issue at all. I initially chose not to leave a review, but two months later I discovered I had been charged for another order, supposedly due to a subscription I do not recall knowingly signing up for and which was not clearly noticeable.After looking into it, I realized several other customers had the same complaint and were also surprised by unexpected recurring charges. Even more concerning, customer service acknowledged this issue in their email to me (attached), referencing a similar complaint from another customer. Despite this, they refused to accept a return or issue a refund.This experience forced me to finally share my original negative review. I am currently using DEOS, a competing product, which works well for me. If you decide to try Zero Breath, I strongly recommend buying only one bottle and making absolutely sure you unsubscribe from any recurring charges. Otherwise, I suggest going with DEOS, which is more popular and reliable. You can find it at trydeos.com.i asked them for a refund which they initially agreed and asked me to return the product then after i returned it by post, they disappeared and not responding anymore. they are SCAM
