Poor service

i regret the day i took a contract with carrack, i called in to ask them to remove device from my old car to my new car they said it will cost me R600 i asked for them to cancel told me stories i then requested for them to divide that amount in to 3 months which they agreed it took them ages to assist with the re stallelation but they never stop debiting....debitting amount that we didn't agree on is been weeks now asking for the recording between me and the consultant still no luck all they do is debit money from my account....poor service..i can't wait to get the recording to take this matter further...
