Telkom poor customer service

I've been having problems for months with Telkom not deducting my account on the agreed debit date. This does not only affect my credit score negatively due to "missed order" status. Recently Telkom have deducted on the wrong dates again, leaving my account in a minus. Then they debited double and are stating they have not received my payments. The one payment for my data sim are successfully debitted every month and Telkom claims I am in arrears. My Telkom accounts are currently both suspended since 04.04.2025. I have email communication of the instore employee Mr. Mark Marinus who is claiming my accounts are suspended due to "Telkom system updates". The data sim I use for wifi at home. I have been without data(service) for the past eleven(11) days.
