The worst service ever. More useless than this I have never seen.

I have received nothing but the worst service from Supersonic. We have to constantly call in as the FLTE service we have constantly goes down. I spend hours on the phone and get no assistance and always being sent to different departments. If I'm not told that the account is not found on system then it's a matter no FLTE being registered to our account. Yet they could easily bill. This is a failure of service and of canceled we will not pay the clawback fee and the failure to deliver the service is essentially breach of contract is it not? Even when promised a call back. Nothing ever happens. I expect a prompt resolution with a breakdown of what happened and why.
