Several attempts to cancel the service which I didn't contract in the first instance and then I gave up. I disputed the bill for $124 and they said they would get back to me but never did. In the end, I paid it on 6/10/20. In early-mid November I get a letter from a debt recovery agency that's impossible to contact and I call ADT- despite quoting the receipt number the extremely rude person in the billing department refused to sort the problem and said they will get back to me. I called the next day - the guy I spoke too told me that that they had not done some processing or other - so as I understand this you can pay them but their systems are so poor they may not recognize it, and then with no cross-check happily pass the account to a debt collector. The guy I spoke to, said while he could correct whatever it was he could not solve the hand over which was another dept!! I asked for confirmation that the problem at his end was resolved and he promised to email me by COB - he did not. And that is entirely consistent with the track record of this extremely poor business. Stay away from this poor service dishonest mob. read more
