incorrect Debits and overcharging

Hello, I'm writing to bring to your attention an ongoing issue with Telkom regarding incorrect charges. Last month, we received a message stating that we owed R712. After visiting a Telkom branch, their agent investigated and found that the debit failed due to their system issues, despite us having sufficient funds. We provided a bank statement, which they verified, and acknowledged the error. We then manually paid R350 on June 28, which was delayed by their debit collectors and reflected on their system on June 3. However, at the end of June, they debited R712 again. We returned to the branch, and they assured us that the incorrect charges would be refunded to our account. We were informed that we only needed to pay R24 for the current month, which would be adjusted against the refund.

However, on July 25, Telkom unexpectedly debited R736 from our account, despite owing us a refund and only needing to collect R24. When we visited the branch again, they explained that the debit hadn't updated on their system and asked us to return on August 4 to resolve the issue and refund the excess amount. Since then, I've been receiving messages stating that we owe over R900, which is incorrect given that Telkom owes us money. I would appreciate your assistance in resolving this matter as soon as possible.

You are draging my name into to mud and financially costing me with all the petrol I use going up and dow to your branch at mall of the South.
