No refund, pathetic customer service, no communication.

made a manual deposit into my Telkom account and the a debit order went off my account. On the 5th of January 2018 I called the call center to request a refund. I was told that they will forward my refund request to the billing department. I was then told that it would take 9 days for the refund. I called I on the 15th of January 2018 and I was told that there was no refund request put through on my account but I must remember that a credit was put on my account and they won't debit my account at the end of January, I told the that I didn't want the credit I want a refund that was what I initially asked for. The agent then told me that they put a pop up on the screen for the billing department to see...I called o the 16th of January 2018 to check if there was any thing that was put on my account, to no surprise that was not done, I was again told about my account won't be debited this month again my response was the same as before. Then the agent told me that she would ask the manager to send an email to the billing department to do the refund of which would be done within 24hours. I called on the 17th of January 2018 to see if any message on the account, the agent told me that I should wait for the 24hours to lapse and if still no refund I need to call back. OK so I called again today the 18th of January 2018 and was told that my case was put through to an agent at the billing department and they will contact me for my account details, of which they have on my account. The agent then told me that if the agent at billing department is on leave then the case won't be dealt with, surely if you are going on leave your cases should be handed over to the team leader to split between agent that are at work. Anyway I asked to speak to the manager or supervisor, was placed on hold and the agent tells me that I must remember that my account is in credit and won't be debited this month.... No I asked for a refund. Guess what, the agent cut the call on me.
