Must say, not impressed. They recently bought out the company that had provided service to my…read morefamily for years. They seem to bait and switch to get clients to pay for "service calls" when the system probably wasn't functional (while they were monthly billing us, and take advantage of elderly customers to get them to pay expensive hourly rates for customer service. I would not recommend them.

Buyer Beware!!!!!! Wouldn't even give it one star if I…read morecould. Their customer service SUCKS! My alarm system has not worked right for over a year. First time was told because my landline was disconnected and I only had cell. Said that was strange since my land line was disconnected years before. Was assured this was the issue. Paid 100+ for fix. Alarm still doesn't work now pad says bf. Trouble shot over phone no fix. Told it was because of weather in Michigan (I live in Massachusetts). Told to wait a few weeks and it would resolve itself. It hasn't. Call again so sane trouble shooting...no fix. But they still charge me 70.00 a month for monitoring even though system is not in working order to monitor. Now on hold for 20+ minutes to cancel my service. Could get rep. Immediately to add or change service but why the long wait to cancel. Buyer Beware!!! With so many other options out there stay clear of ADT unless you want to throw money away for no monitoring. Update: Five minutes after posting and I am on the phone with ADT. The offer is now to upgrade my system. While that is satisfactory, I should not have had to post on Yelp and google for ADT to step up and make good on a customer who has been with them for 16 years.

Signed up for a 3 year contract that expires at the end of this month in Amherst. I called earlier…read moreto let them know that I wanted the service to end with the contract, but they told me I would be charged a cancellation fee if I cancelled then - I explained that I simply wanted my contract to expire without further charges and they told me to call before the contract was up. I called today to ensure services were cancelled; after being on hold for 8 minutes, I was transferred to the department that handles contracts. I was told that I couldn't cancel because I had a balance that was more than 120 days past due. I explained that I have automatic billing and a zero balance; the rep told me we could "settle" and pay a lower rate for two months and call it a wash. I refused and he said I had to talk to billing. Another 5 minutes on hold and billing confirmed what I already knew, then sent me back for cancellation. After 35 minutes total, they confirmed I had a zero balance but literally tried to get me to renew 5 times and offered a discounted rate. I repeatedly declined and was informed that it takes 30 days to process terminations, so I have to pay for a week even after my contract expires. ADT staff are obviously trained to upsell and not take no for an answer on cancellations and I am very suspicious about the claim I had a balance due being used as fraudulent leverage to squeeze a couple more months of fees out of me. 42 minutes total for a transaction that should have taken less than 5 minutes. Awful customer service. Edited to add that they called me 2 days later to ask why I cancelled and offered me a holiday special. It's easier to quit the mafia.
