The first time the engineer came, he didn't even install the equipment properly. My shop is very small, so it's only an hour's job. However, the engineer spent the whole day on the phone outside the shop and kept on delaying the installation of this equipment. As I said, he didn't even install anything properly, despite the fact that he spent the whole day doing this. The control panel was incredibly difficult to access and the system hasn't even worked properly since the first day, with also the sensor dropping from the fitting. I reported this to ADT and, without my consent and without even asking me, ADT sent an engineer to my shop, not even informing me that this appointment was chargeable. If I knew this appointment would have been chargeable, I wouldn't have accepted this. This engineer was only in the shop for 5 minutes (not 44 minutes as stated in the attachment), so how is it justified that I am charged £883 for this? If you don't reverse this charge, I will cancel this contract with immediate effect, cancel my domestic ADT contract and remove all ADT devices from my premises. This is completely unacceptable and I am angered by this, so please sort this out. Note: I was supposed to take the contract for my shop at the end of January 2024, but your sales rep pushed me to sign in December, telling me the prices were rapidly going up.
