After around 35 years of being a loyal customer, I finally decided that the annual cost was just too much, and discovered I could buy and install an entirely new system elsewhere, with monitoring, for less than the annual maintenance fee. In fact I could buy and install an entirely new system with monitoring from elsewhere every single year for less than I pay ADT! It took a string of e-mails and calls to arrange an uninstall appointment - that they didn't turn up for. The final insult from ADT is their totally blunt refusal to uninstall the alarm unless I pay their eye watering fee of £180 for the first half hour plus time after that. They didn't tell me that when I booked the appointment they didn't turn up for. Even although there are many years when I haven't taken the annual maintenance visits I paid for in the annual fee, this counts for nothing. Unbelievable - how they still have any customers left at all with this sort of "customer care" is a mystery.
