Telkom treats its customer shockingly

Telkom are so inefficient. I have sent an email complaining about their lack of service and customer care, and received no reply! To cut a long story short, we cancelled a Telkom service when we moved. We received no notification that we owed an amount of R85. We wanted to apply for Wifi, and were then advised that we owed the amount. We paid it immediately, and it is reflected in their accounts dept. However, the payment hasn't been updated on their system, and is still showing as outstanding, preventing us from applying for the product! We paid this more than 2 weeks ago, and have called and gone into the Telkom store to complete our application. Each time we are told the matter will be escalated and sorted, and someone will get back to us. Up until today, nothing has been done. We are so disappointed in their service, as we have been their customers for many years. Can someone please sort this out now, as this is totally unacceptable.
