Do not even know their own processes

Here we go again. My contract is ending end Nov (thank goodness). Call Tracker and yet again none of the consultants can help on what is the process to cancel my contract. They answer questions that I have not even asked, I just want to cancel my contract end of Nov nothing more and just want to know do you need notice in writing and is there a cancellation period and no one can answer these questions. Now my question is if they cannot answer a simple question like this how they are going to assist me the day when I'm in trouble and need their assistance. Can someone just answer me on the process to cancel my contract at the end of the contract period so that I can use a different company that cares about their customers. This is not the first time I have problems with Tracker since the start of the contract worst service ever received from a company in my life.
