Breach of Contract

I'm so unhappy and frastrated with the service I've received from ADT. I've signed a 2 year contract with them December 2014 to pay R295 per month, but since November last year my premiums increased because they've decided to merge with Fidelity. What does that have to do with me. I feel that is BREACH OF CONTRACT. Then again from April the fees went up again, which I know was due to the Vat increase, but last month my premium went up AGAIN an even THIS MONTH it went up AGAIN. Could some one please tell me why. It's my bank account, you can't just take more money as you please. I can't wait for my contract to finish, because all I've received was BAD service from you. If you don't take more money from me, you don't come out if my alarm goes off OR you take more than 30 minutes to get to my house. I'm only with you because one of your control managers convinced me to give you another chance, but since you don't honour the contract we went into. Why don't you release me from this contract so that we can go our seperate ways!!!!
