Auto payment problems

I have experienced problems with the auto payment system for a couple of months, I was hoping it would be corrected by now but it seems it's not the case.

The auto payment on my account has been set up to pay the full outstanding amount on my credit card account from my cheque account on the 1st of every month but every month it seems to only pay a minimum amount. I have made numerous phone calls to the call centre to try and get this rectified and every time the solution seems to be that I need to make a manual payment from my cheque account to the credit card account.

Although inconvenient, this is not the end of the world, the problem I have is that interest gets charged to my account even though I specifically get confirmation from the call centre agents that it would not be charged as a result of the auto payment system not functioning correctly.

I am not wasting any more of my money phoning the call centre and getting these interest charges reversed - fix your system and reverse the interest.
