Cancellation

I'm moving home and have been calling ADT since April to cancel my service, the agent answers and transfer my call to retention I will hold of a while then I'm either told the agent is on lunch or on a meeting. Really how can such a reputable company have one or two people at the retention center.im beyond dissapointed.ADT I want to cancel my service get in touch with me ASAP on *** since well no one is willing to assist in your contact center.This is unacceptable your retention service is poor.
