I have given 1 star to write the review but if I could I would give -5. Changed our WiFi provider which stopped our cameras working and was informed an engineer had to visit our property to update the system, I was told this couldn’t be done remotely. An engineer was booked on 8 separate occasions and each time they didn’t come. I was taking time from work for these appointments with no show. Sometimes they would call at the end of the day to say the engineer ran out of time, others I got no call and would have to call them the next day to rebook. When I told ADT about my frustration over this they weren’t interested. I informed them my employers were getting annoyed with me taking time off, they apologised and promised an engineer would come. Each time I booked I spoke with somebody new and that person didn’t seem to have notes (or made out they didn’t) to show previous contact, or that I had waited in lots of times previously. On about appointment 6 I asked for the girl I spoke with to only book in another appointment once they knew there would be an engineer available to come, that it wasn’t fair for me to wait in so many times for nothing. She told me I needed to book or the only alternative would be to close down my account, I was so shocked by her lack of empathy that it upset me. The manager I dealt with eventually was uninterested, was hardly available to take my calls and took days to answer my emails. When I did she kept apologising and saying the service wasn’t good enough, but then it would happen again. I insisted on speaking with an area manager in the end and he sorted an engineer to come from another area telling me there wasn’t one currently in mine. I then doubted there was ever anybody assigned to attend the previous appointments. These non appointments happened over a period of 3 months, all the time the system not working. I called today to cancel the contract because the cameras aren’t working again. I explained to the man I spoke with what had happened previously and that I couldn’t put myself through that situation again as it was too stressful. I asked if he could take the months notice period charge off as a good will gesture, given the reasons for cancelling. He was very abrupt, and told me that we were under contract, that if I’d stayed with them he could probably do something, but as we were leaving we would be charged the last months service charge. He showed no empathy for what had happened previously. I have never received such shockingly poor unhelpful customer service in my life through the whole process, and I would advise anybody to steer clear of fitting ADT alarms in your home
