Incompetetence is an understatement

I queried with customer services an overcharge on my account. It took 3 weeks to get a response and they said they had passed my query to cancellations to cancell a contract that they automatically changed to a month to month contract and doubled the price. I have tried to call to check whether this has been cancelled. I spent 5 minutes on the phone listening to their stupid UNISA adadvert then couldnt transfer to am operator as they said my option selection was invalid. They clearly think everyone has tons of time to waste waiting on a phone talking to a robot.
