******* debits

I do not have any accounts with telkom yet they have been debiting. I keep revising the debit yet they keep pushing it through. This has been going on for about 6 months now. They keep changing the reference and the amount to make it go through. This is ******* as when a transaction fails you contact the person to clarify not just keep pushing it through. Also if a transaction fails more than twice in a row it is ******* to debit again without a new mandate. Well FNB keep pushing it through so they obviously don't know the law around the very product they sell.
