Bad service from Telkom and Mandy Ngubane (call agent)

I logged a dispute relating to the incorrect billing of my account on the 2nd and 15th of October.

ref# ********** 1 & ********** 5 respectively.

I had to phone various times to resolve this, only to receive promises which are never kept.

When I phoned today, 2018/12/04, the call agent (Mandy Ngubane ) just put the headphones down and walking away and after a while she came back just to put the call down. She was also extremely rude and has no idea about what is going on and don't even show any interest to understand the situation.
