Rather consider another ISP than Supersonic

Had terrible customer service from Supersonic. At first I was happy with the level of service received from Supersonic, until the beginning of this month where my line was just cut off for no apparent reason. I've been calling multiple times per day for the last 8 days and received no help and my account is still offline. Received multiple different reasons to why this occurred, cancelation of my account (which I didn't request), account suspension, failure to pay etc. I have a debit order that goes off the end of each month, which is all in order and I have sent through proof of payment for last month. Apparently the system was offline... I have been told that my account would be activated within 4-8 hours multiple times over the period of 5 days. Everyday I spend more than an hour to get to a resolution with a consultant but which seems to end up being empty promises. I won't even go into the amount of I've been put on hold for countless hours then the call ended. At this point I just want to cancel with immediate effect due to not receiving a service I am paying for, as it seems this is a breach of contract. Although at this point in time I'm not sure what to do anymore since looking at the other reviews others are either having issues cancelling and having billing issues or are charged cancelation fees.
