Appalling Service! Having happily taken my money on a monthly basis for the last 3 years I must say that the customer service is severely sub-standard. As a customer I do not expect to have to chase the company to administer my annual service and then to be told that I can only have a service before 12 p.m. even though they claim to be a 24/7 service provider. I have cancelled my contract and now they want to charge me over £100 to deactivate my alarm system! I requested that since the paid for annual service had not occurred I should reasonably expect that in lieu of this service they should deactivate the alarm free of charge. They refused to consider this sensible proposal. ADT Customer Services called me to try to resolve the issue. They failed miserably. Instead of acknowledging that they had made little effort to follow up with me when I did not receive the letter to schedule a service in spite of having both my e-mail and my mobile number they offered, as a gesture of goodwill, to arrange for a service! I had already payed for this "gesture" through the monthly payment to ADT which included an annual service. Someone needs to explain to them the definition of "goodwill" When I queried the customer service employee as to why, if an engineer could be sent out to "service" the equipment they could not simply disable and deactivate the alarm system instead since I am cancelling my contract. The response was that service was chargeable (£100+) and was different from a service. I asked whether their engineers were not capable of both servicing and deactivating? Yes, logically, they were, so my question is: Why if an engineer can schedule a visit to service the system that same engineer can not simply deactivate rather than service??? Ridiculous response and no help whatsoever. So much for "goodwill". Avoid, Avoid, Avoid! I should have read all the reviews before retaining this company and it would have been fairly obvious that this company is not customer oriented, is not fair and has more bad and poor reviews then anything else! Very disappointed and very annoyed.
