Extremely disappointed

I telephinicaly Canceled my contract with Adt on the on 30th of August, I was advised that a month notice that will apply the contract will be terminated by the 30th of September of which I understood. I didn't get any confirmation I called in again I was advised to send an email. I got a call this morning where by I got interrogated about the new security provider why taking them and how much is their premium, where is their control room. The lady said the calation will be effective from the 1st of November. Why must pay I pay for two months premium with no service rendered. I don't accept this kind of **** ADT you should do better I've been with you for years and this is how you thank me. The consultant also mentioned that they will come and collect their system, when you upgraded the security service I was prompt to buy some of the material the battery and et. So now which part of the material are you going to collect? The two months notice its not acceptable. I don't take it.
