Annoying Service and Disconnection

I was disconnected for the 4th time this month, with no reason. No one can explain and get this to stop. My accounts appears to be in arrears yet I have already paid. They have reconnected me 3 times as they cannot see the reason why i was disconnected cause i have paid. Its frustrating to call the call centre all the time to sort this out, especially if you get *********** people on the line.
