Terrible Service by Telkom

I have been trying to cancel my contract subscription with Telkom since January 2016, Every time I call they tell me to wait for a cancellation guy to call me back, but guess what it has been 5 months now fighting the same issue, every time I call to enquire they tell me excuses like “we are escalating the issue”, “sorry we have sent your forms to the wrong department”, “someone will call you soon” blah blah blah….meanwhile my money is getting debited month after month for a product that was supposed to be cancelled 30 days after my request. My last follow up was last Sa****ay where I again filled in my third cancellation form and was told again someone will call you soon by Wednesday, but till today I'm still waiting for that call #TalkAboutBadService
