Pathetic service from a rude consultant

After a whole day of not being able to make outgoing calls or messages yesterday, I managed to use a colleague's phone this morning to call MTN's call centre. I spoke with a consultant called Zanele and I asked her why my services were suspended even though the debit order was successful. She advised that it was a network error and she couldn't explain to me what that was. I further asked her if I was the only one affected, she told me she cannot tell me that information.

I then asked to speak to her supervisor as she was failing to give me any information and this was the second time this is happening. She asked me to stay on the line and then dropped the call on me immediately.

I do not appreciate the attitude she gave me and the way she handled my request. It was very rude of her to drop the call after asking me to hold. If the manager was not available, she could have advised so. I still need an explanation as to why this keeps happening to me and why they can't give me any further details after the huge inconvenience this "network error" has caused me!
