Over charging under delivering

I am at a loss of words over the ridiculous amount that ADT charges for call out fees to clients who have been with them through 10 years and 3 moves. My house keys were ****** over the weekend, and they now want to charge me close on R600.00 JUST for the call out fee. That is EXCLUDING the remote. Not only that, they have deducted R550.00 off my account for a reason unbeknown to me. I am dumbfounded. I cannot believe that ADT can blatantly ***** from their clients in broad daylight. I refuse. I will take this to the ombudsman if need be. But they aren't going to continue to do me in anymore.
