I was with XXXX for XXXX+ years. I decided to not renew because I was not satisfied with them. I was on a month to month contract, but, to simplify my life I just paid it annually in advance each year. The last renewal bill I did not pay. I switched alarm companies in XXXX. That same month I got a call from XXXX XXXX asking why I did not renew. I told the supervisor why and he stated he was sorry and asked what he could do to keep me as a customer. I told him I already switched XXXX and there was nothing. He said he would get back to me with a proposal anyway, I said fine, just email it to me. 
I never got that email and therefore did not even think about it. Sine that phone call I sold my home, purchased another and never gave this issue another thought until early this year, I noticed a collections on my credit report. They are claiming I owe {$330.00} for alarm services. Then I got to thinking about what happened. I had some questions. 1 ) Why are they charging me for almost a full year of service? 2 ) Why did n't the supervisor tell me this on the phone in XXXX when he knew I was with another company? 3 ) How long does it take to cancel a service for non payment? 
I called XXXX XXXX and they said they do not have the records anymore I have to deal with the collections company. 
I sent certified letters to the collection agency ( attached ) trying to resolve this and they are refusing my offer. I offered paying up to the time in XXXX that I spoke with the supervisor even though I feel I owe nothing. I think it is more than fair. I now understand that they require an advanced written notice to cancel. I think the supervisor had an obligation to notify me of this when I spoke to him on the phone. There was no way for me to know or remember this procedure from XXXX years ago.
