ADT is the worst!
These guys are the biggest scams. We have been trying for 6 months to cancel our account. They will just give you the runaround. They put me on the phone with a guy who was the scammiest smooth talker you have ever heard of.
After 30+ years of service, they have fought our cancelation tooth and nail. We had to call our bank to reverse the charge. BUYER BEWARE. They are a horrible company.
