Telkom - BAD Service

Telkom has the worst service with their call-centre. they provide you the option to have assistance in your mother tongue, but when you get through to the call centre, they do not have anybody in that centre that can assist you. On the advise of the consultant, you then have to drop the call and call again, but when choosing a language, you have to choose Sotho as a language to get assistance in Afrikaans. Where is the logic in that? I have a challenge in getting the correct information regarding my account. I get an invoice for R 2,904.69 and pay the outstanding amount (when I eventually get the correct information) of R 1,468.22, but the amount of R 2,904.69 still gets debited at the end of the month. How is that even possible?
