Very unhappy new client

So after 2 hours worth of holding time and conversations over the Customer Care line (over a span of three days), I am beyond irritated. I understand a person can only do so much but I don't appreciate being told to call back or just be patient if the issue is not being resolved. Firstly the debit order for the FIRST month of our new contract, doesn't go off. Secondly, the gentleman in the shop says I don't need to make a payment as the deduction is due to go off double in March, as they back date payments. I asked him to please make sure, as I don't want my account to be suspended in the middle of March... Thirdly, the account is SUSPENDED!!! I am fed up. I give up and I'm a new client. This doesn't bode well.
