Finanial ****

About 10 days ago I received a call from Telkom informing me the speed of fibre will be increase. I did not request this. I asked how much extra this will be, the lady said she will call me back. I didnt receive a call. And I never agreed to paying more. YOU DONT HAVE MY CONSENT, that is contract breach. So I am therefor allowed to cut ties, and will find another provider who wants my money and will not **** me financially by forcing me to just pay more
