Sales ***** and Incorrect billing

From 30 March 2020 I had an Unlimited Home Fibre 10mbps package for which I paid R799 per month based on the initial agreement at the store i signed up for 699 deal and during December when I checked my statement I was suddenly upgraded to 20Mbps fiber without my concern I asked the salesperson at the store multiple times whether the total amount I would be paying – the bottom line on the statement – would be R699. He said yes multiple times. I asked, again multiple times, whether there are any hidden costs he said no.

I have since been billed R1400 for April , R799 for May, June, July, August, September, October, November and R859.51 for December . I contacted the billing department. The consultant told me that I was in incorrect package and referred me to the sales department. The sales department said that the discrepancy must be due to a voice package being included and that is part of the package it can't be canceled and I should go to my telkom portal and downgrade the package to 10 mbps even I didn't upgrade it my self, since the initial agreement I can't access my telkom portal it refuses to accept my credentials and she refused to fix the package issue because I have never requested to be upgraded to 20 mbps and per the initial agreement I wanted the 699 deal.

That was not the agreement! The agreement was that, as I said above, everything would stay the same, apart from the line speed and that the total monthly cost would be R699.

Please correct this. Refund my overpayments, and adjust my billing going forward.

Thanks!
