Testy Telkom

I cancelled my contract with telkom on the 12 September. To date they are still deducting money from my account without me opting for an upgrade. My debit has dropped by R 100 but the bulk of it I am still paying. They did not inform me to begin with that my contract was ending, I had to go in myself. This is apparently their modus operandi. They say to end a contract takes 2 months yet to sign up for one take less than a day. I am so irritated that no one even bothered to call only now that the contract has been cancelled are they sending me emails to remind me to upgrade. I have been a customer with telkom for many years and find it most irritating that quantity is valued over quality service. Telkom is at the top of my rank for mobile network but it appears much is changing.
