Please be warned, this is the most crooked company I have ever done business with. My husband and I had an ADT security system installed in early April. The full installation charge was supposed to be $440 as stated in the contract that we signed. To account for the $440 charge, my husband wrote two checks, one for $220 at the time the contract was signed and one for $220 when the installation was complete. ADT cashed both checks for a total of $440 but also used one of the checks to make an additional electronic charge of $220 that was never authorized. Therefore, they ended up over charging us by $220.
