Stay away from ADT - They are the worst by far!!!

We have been with ADT now for 7 years. In those 7 years we have been ****** three times. Each time ADT pitched up long after the house had been cleaned out. We had an attempted hijacking in our driveway. Activated the panic button. ADT never even bothered to pitch up. We have now finally decided to join another armed response company. When we joined them, they removed our existing alarm to install theirs. Asked the salesman what will happen if we cancel ADT? Will they then re-install our perfectly working alarm that they removed? "Yes no problem" was the response. On 31-08-2017 we gave ADT notice and instructed them to remove their radio & alarm asap and to re-install the alarm that they had removed. After much arguing they agreed (Mpho @ call-centre). It is now more than 3 weeks later and we are still waiting. Made various phonecalls and received many promises (that's if Mpho has the decency to answer the call or to return the call). Sent various e-mails - all to no avail. They simply ignore you and don't get back to you. This is how they treat their loyal customers. If you are considering joining ADT - DON'T! YOU WILL REGRET IT!!! ADT you will, in light of the above, not get your alarm back unless our old alarm is re-installed and working, as per our agreement. New armed response is today coming to install their radio. Because you have failed to meet your obligation and honour our agreement we will be using your alarm until such time as you have re-installed our old alarm as per our agreement. Under no circumstances will you remove your alarm without re-installing the alarm that you removed. Once the old alarm is re-installed to our satisfaction (and working) - then only will you be allowed to remove your alarm from our premises. We deeply regret the day we signed up with ADT. Big mistake
