POOR PATHETHIC SERVICE FROM TELKOM

The worse service that I ever could imagine. I have received a wi-fi databill of R 1 831-86 for December 2019. I visited Telkom at Menlynn on Saturday 04/01/2020 they could not assist except sending a query through to their call centre. I was called a couple if minutes later from the call centre. They also could not assist me except I was given the 10213 and 10210 .i called them no help and then given 081180 number. I was sent around in circles. Nobody could give me a proper explanation why I was billed out of bundle and why my data keep on running while our agreement was 10gig during the day and 10 gig during the night. When I requested my original contract agreement I was send from pillar to post. Every month last year when my data was finish I could not access extra data now suddenly during December there extra out of bundle data provided without me being consulted or agreed upon. This is **************** and poor ethical business practice . I need serious assistance in this matter.
