Poor service

I had a horrible experience with telkom, I settled my account in February and I asked them to closed and send me a cancelation letter as I was told to pay the device penalty and all other fees occurred and owed. On the third month, they tried to deduct my money, I called them as I was calling them for the 3rd time wanting the Cancellation letter. I was told im owing 1429 which they call it Cancellation fee which was included on the settlement amount as i states i want to cancel the **** contract, i asked for the recordings as it was stated to me that it was fully paid. Up until today I keep calling and they don't resolve the matter. People should stay away from that **** called Telkom.. I need my 1429 from my contract ***
