Forced to pay for the plan I never app**** for.

I app**** for fiber end of November last year that was 499, I received bill for 579. I called Telkom to complain and requested for them to rectify the error. I was told that I should pay the extra amount as I had already enjoyed that benefit, I asked the agents that how I was to know that I was enjoying a wrong benefit. I involved the person who assisted with the application and then the bill shot up further it became worse, and it was changed to an even more expensive plan of 854, up until this day my query has never been resolved. I get sms's that I have been handed over as I find it difficult to keep paying for the wrong plan. each time I pay what I have actually app**** for I keep getting a shortfall on my payment. I was once transferred to some so-called manager, billing and agents and no seems to be helpful, and no one is able direct me to the channels to complain.
