Worst call center service.

I recently have been experiencing loss of network when trying to make calls.

When calling the call center, I am expected to provide private information, which I am not comfortable sharing over the phone. The agent then refused to help me with my query. I asked to speak to a manager or supervisor, and I was told that they are not around at first, and then they are not there. The agent put me on hold for about 5mins for some reason, I suspect she wanted me to hang up. After returning to the call, she came with some sloppy advice and still refused to escalate my query to a supervisor or manager and said I have to go into a store to take the query further.

I have been with Telkom for nearly 13 years, and this is the worst service I have ever received from them.
