Supersonic Service

We had 3 accounts with Nepic and NEVER had any problems for nearly 3 years until Supersonic took over from them a few months ago. Since then we have been battling to get their accounts system sorted out, we are frequently sitting without any wifi, our emails are ignored, when we call in to report that we are without wifi (it happens so regularly lately) the phones are dropped after being number 21 in the queue before speaking to anybody, our emails are returned 'no attendance at this mailbox', we can not report a problem on mail we have to call (even if the whole area they supply with wifi is down), they do not send messages informing their customers that they are aware of outages, and nobody returns our calls! We NEVER had any problens with Nepic. Since Supersonic took over we pay for service we do not get. In the past I bragged about the excellent service we got (when Nepic was in charge), now I want to change service providers. Their service is absolutely pathetic! Maybe I hoped that Supersonic will follow the example Nepic set, but they can not be compared. The data I have to buy to remain online is getting more than the premium we pay for uncapped internet per month, because they are 'off' so often. I
