Incorrect billing dates and debit orders on customer accounts to force the R200 penalty fee

Good day I was instructed to write this complaint for him, with regards to incorrect billing and debit order dates. your company is messing up his credit record with these failed debit orders which are being done on incorrect dates and thereafter the charges being levied against this contract, I will escalate this further because I believe he's not your only customer who you are doing this to. It seems it is being done on purpose so you can charge your customer R200 penalty fees, his contract debit order date is the 31st of every month yet you continuously ran the debit order on the 25th so can you charge the penalty fee on the account, I find this ************.... if you are doing this to 1000's of your clients pretty much ****ming your customers.
