Call centre unreachable,incorrect&inconsistent billing.

In my contact we agreed that I will pay R800 every month which I never failed to pay.Sometimes they will fail to deduct on an agreed date&i make Eft payment.The next month I make an Eft payment&still they deduct&i go back to my bank to make a debit order reversal which attracts charges.On the 21st of this month they tried to debit an amount of R975 which is a bridge of our contract because my premium is R800 and it is not payable on that date.I went to the Wonderpark branch to lodge a complaint on the 22September but I didn't get help.I asked them about the whole dissatisfaction but they made me to hold on for more than an hour telling me that they will come back to me which they never did.I have to date paid more than R500 in bank charges due to their poor administration&to make matters worse they are now deducting R975 from my account which is a bridge of contract.I hope you find the above in order and give it your immediate attention.
