My contract ended on the 15th of September and I sent an email to Telkom on the 2nd of September requesting to cancel my contract after numerous attempts of trying to call the customer care number with no success. I even went to the store to cancel but they too couldn't assist because the cancelations department never answers their phones. Spent a good 30 mins in the store trying to cancel my contract with no success.
