False advertising

Good day Last week I was called by TELKOM MOBLILE agents several times . I spoke to Mohamed, and he told me that my contract was due for upgrade . I told him my router, cell phone and tablet are still fine , no need for upgrade . Then he told me as I am a good and loyal client, I qualify for more data and less money to pay . I asked him specific to put this in writing and he said no problem and even repeat my e-mail address. The next day he called again and said my tablet can get now more data for less money that I pay at the moment My contact with Telkom is R188 a month and only become more when I use my router when away from home ., as I have uncapped data at home and will cost maybe R20 to R30 more On the 31 OCTOBER my debit order was processed for R671.75. Since then i had no success in cancelling this and get my old contract back as it was The no supp**** to cancel this new upgrade was 081180. Ever since no luck. phone several times and got hold of Melissa which put the phone down in my ear while trying to explain my problem. I will not pay a cancellation fee as no communication was received via e-mail s requested. I did not take a new phone nor tablet or router. This was airtime only.
