Moni Smart Security Continued billinig after termination notification Dallas Texaas

On April 3, 2018 I called to terminate my monitoring service. They tried to sell me an upgrade but I refused. After going round on this mulitple times the customer service rep said she could not help me and transferred me to an account rep who again tried to sell me on an upgrade. I finally convinced him I didn't want that and was calling to terminate the service. He said thet they would have to send me an email notification to fill out. This is course they never did. A month has now passed and this week I received a new billing with past due amounts and billing for the period that starts two weeks from now. I also was starting to get harrasing phone calls telling me to pay up as I was past due. I called again and complained that I had already given notification of service termination. They said I had to give them 30 days written notice on their form and then they said I had told them not to send the form. This of course was a lie. I told them to send me a copy of the contract telling me I had to follow their procedure of 30 day written notice when in fact their webiste terms and conditions stated a phone call is sufficient. I told them to send me the contract I had signed and the cancellation form again.

I am to call back again on Monday if I don't receive via email. I am sure it won't be sent as I never signed such an agreement. All I want to do is cancel and all they want to do is string me along for as long as they can to wring more money out of me. As far as I am concerned this is bordering on extortion and fraud.
