Can not do a standard ISP change.

It was suppose to be a easy standard ISP change from 1 provider to SuperSonic. I have now been without any internet for 4 days. Call center just drops you back in the que because they can not help you. They refuse to send you to any senior person. They will say call is with the PMO office but yet you cannot contact them and they can not transfer you. They also handle you like you are a child. They keep pushing the blame to anybody. They use the "Escalate" but it just means we will do nothing further, ot we will open a case for you and then they promise 24 to 48 hours, it is now double that and you still wont get any help! They will even blame the installation which has work 100% for almost 2 years. Vumatel test and say the issue is with them, I have no internet and say it must be Supersonic and yet Supersonic refuses to accept that they might have a problem. 2 individual people must be wrong because Supersonic says so....
