Telkom Stop *****ing people's money

I cancelled my LTE contract with Telkom on the 30 July 2018 due to moving to Germany for 4 months. I first phoned customer care to have it done and they told me that it would cost around R300 as that was the amount still owed on the modem. But that I need to cancel it online. They mailed me the instruction and I thought it was cancelled. They kept on deducting the payments from my account. I phoned them probably more than 10 times to get this corrected. Each time having to wait 30 to 45 min before someone answers the phone. Then they refuse that you speak to a supervisor and just tell that an urgent request has been logged. But still nothing is done. I started to reverse the debit orders and now I am listed on ITC. Telkom STOP *****ING PEOPLES MONEY
