Telkom suspend fully paid up account

My account was suspended out of nowhere after all my debit orders deducted successfully. When I phoned in, I was told that the additional modem I took on that account exceeded the credit limit for the NEXT (future) debit order. Therefore they suspended 4 devices because they did not adjust the credit limit for the additional device! I was told to make a payment to just bring the balance under credit limit and then my service would be restored within 5 to 24 Hours. I made the payment on the Telkom portal and 24 hours later my service was still not restored. I phoned in again and I was told to email proof of payment, which I did. Another 24 hours later and my service is still not restored. I phoned in again and was told that money still does not reflect. How is it possible that a payment that was made on their platform could not yet reflect on their systems! When I enquired if the credit limit has been adjusted yet, the answer is that they cannot see that on their system.
