Day light *******

The amount of R803.78 was suppose to be debited on my bank account on 25th (April) of last month but the debit order it wasnt being generated by RCS and i make and effort to call and find out why because they is enough money in the account and its the same account they have been using all along. The lady told me they was a mistake and she will do the debit for tonight and the next morning still the same. i called again and got the same answer. Now all of sudden they is interest and penalty being added to the loan account and i think someone just ignore to generate the debit order so that the following day penalties will be added.(THAT A DAY LIGHT *******). I phoned today to ask for their bank account number so that i can make the deposit manually inside the bank but the agent put me on hold until the phone drops. This is really getting out of hand and someone just tell me how long will this end?
