Debit order

I have made arrangements with regards to the payments to my accounts. With regards to account ending with 7010 the payment was R953.72. This amount was deducted in February. For the month of March an amount of R1409.07 was deducted. With regards to account ending in 7008. I received a message on Thursday 17/03/2016 that the debit order was unsuccessful. I get paid on the 20th of every month and If the due date is on a Sunday I get paid on the Saturday. Why are you'll trying to debit my account earlier.<br> <br> Please refund the amount of R455.35 for account 7010 and debit for account 7008. The amount for acc 7008 is R715. Please stick to the arrangements as this is really becoming annoying as I do not have the time to keep complaining on Hello Peter. Please sort this out urgently. Please respond via email.
