Grand Alarms

I have been a loyal costumer for 8 years. When I moved I cancelled our service and was told to leave the system in the house for the next owner to reactivate. I was charged for two months I wasn't in the house and when I called to rectify the situation I got the run around. I asked to speak with a manager several times but received no phone call back. The response I got from this company was way below standard and I will never do business with the company again. Extremely poor customer service!
