ADT - Bad Service

After trying to explain people over the phone that we had an issue with the alarm system, I wanted to give ADT a chance to rectify the issue before considering to cancel the contract so I booked a meeting with their Business Sales Consultant Andre. He was professional in the meeting and promised that he will have the issue resolved with no call out charges and get the alarm antenna upgraded at no charge as well because he understands the issue.<br> It has been over a month and numerous emails to Andre but no response at all.<br> After being a loyal customer for many years, I am questioning my decision to stay with them.
