Seems like a scam

Seems like a scam. I have cancelled
The day after due to changing my mind - 15th July. It’s now 11th August and I still haven’t received my refund. There is no clear email that you can liaise with if you have a problem - so it’s difficult to gain a paper trail. The email on my receipt form when I first booked is actually outdated and unmanned. Very misleading. Stay clear.

ADT provide services to MBR Acres who breed 2000 beagles puppies each year for the animal testing industry. These puppies are sent to laboratories at 16 weeks old to be tortured. I cannot think why a company would want to do business with MBR Acres unless they have no morals or humanity or conscience. I am horrified that they are making money from animal abuse

Informative and Patient

Informative, patient and understanding, your installation engineer quickly realised that my wife and I struggled with technology at any level.

He was friendly with an excellent personality and we felt very comfortable in dealing with him.
