Worst Service Delivery Ever

I had to cancel a business account I had had with Telkom since they couldn't provide service to a new premises I moved to. That process took almost one year... They still owe me money however, as I had credit on the account. And that has been an ongoing battle for the last three months too ever since I had explained the situation on the Hello Peter site in November 2017. Telkom has all the necessary documents to do the refund, but NOTHING happens. I have just received another statement showing the credit though!!! I am utterly dismayed and frustrated. I would like to warn everyone: DO NOT USE TELKOM AS A SERVICE PROVIDER.
