Cancelled ADT Service

I cancelled ADT Service at both my houses on the phone with George ( ********** ) from Sasolburg Branch on the 23 June 2017 and took out their radio's the same day. He said it is fine and he will send somebody to come get their radio's. I am still awaiting someone to get their radio's from me. I paid end of June my debit order for June's bad services. I paid end of July my debit order for the 1 months cancellation fee. now ADT took my money end of August aswell??? Now when I phone them to refund me they tell me that I should have filled cancellation forms from them. That was never been told to me the day I phoned and cancel. They can't even see from their side that from the 23rd June there was no signal from one of the houses but they just want money. Now they want another R 900 for cancellation??? Hello Peter please help me get back my money... All calls has always been recorded and now they can't go back on their calls all of a sudden??? I Have phoned them in 2 months about 200 times???
