Unfair Billing and Bad Service

This my account number *** I have a billing query, for this month I was charge R1100 for Retail Fibre Broadband 10/10Mbps. This is not what I signed for. I contacted Telkom live chat, I was chatting to Zinhle Zwane who took 5min to type 2 words and at the end decided to rudely disconnect the chat without any answers. It has become so difficult to get answers from Telkom. This is shocking there are 102003 reviews all 1 star and Telkom never respond. I would appreciate if Telkom could make contact with me.
