I am done with you guys, stop debiting me!!!!

Took out a 10 Gig plan with an ipad about 2 years ago for R279 pm. At month 23 I call the call center to place my 1 months notice to cancel the contract, I was then told that this cant be done over the phone and I need to go into the store. I go into the store and fill out the forms. At month 24 I get debited for only my subscription and not the device which is correct. Now think that everything is done and dusted with Telkom, You guys then go and debit my account for R617 this month, I mean like what the heck!!!!!<br> Call the call center they say you need to go to the store, go to the store they cant understand why I was debited but also cant assist so they call the call center who still cant assist and asked for the consultant to log a case, still now still no feedback. Telkom stop this please, stop robbing me, where is your ethics? This number on the account is not even mine!
