No internet connectivity

Lodged a complaint recently with Hello Peter as I was being invoiced for two services incorrectly. Within a day the issue was corrected and I was initially very impressed.

HOWEVER, one week later my internet stopped working despite my account being overpaid. I have phoned numerous times and still it is not working. A contractor was sent out to my house yesterday afternoon and they said they don't know what is the problem. I phoned the call centre a short while ago and they claim there is no record of me ever having lodged any query or complaint. So how did the sub-contractor magically appear at my front door if not sent me Supersonic?

I find it strange that a few days after lodging a complaint about being over charged my internet stops working and somehow nobody knows why! Nobody seems to be willing to be helping me now.

I have also received an email saying that my ticket has been closed[SST036806] yet Supersonic claims there is no record of any queries or complaints. Where does this ticket come from then?
