ADT not to be trusted

In the past I have had to complain to ADT for breach of contract. I signed up with ADT about 2 years ago. The contract indicated first 3 months free then fixed amount for 2 years. Within the first month the decided to break the contract agreement by taking a fee. I had to spend hours on the phone send them copies of their contract to get the mess sorted. Then they increased the fees, without any notification under the false pretence that the fuel price has gone up. When I enquired about joining ADT I asked the sales person if ADT does engage in this practice of increasing when the fuel price goes up and he indicated no they don't yet ADT does. I once again spend my time complained and received an agreement from ADT that my fee will be reduced to the original amount and the over charge will be deducted from my September fee. No this turns out to the third time that they had decided to ***** money from me the way I see it. ADT is there and the service you pay for is to protect you yet they try their utmost to see if they can ***** from you. The petrol price has come down again but ADT did not reduce the fee they just keep on breaking their agreements. I will be cancelling my contract with ADT, because they cannot be trust when your security company *****s from your bank account.
