Being ******

I had a tracker unit on a vehicle that I sold in Feb 2017. After numerous attempts and emails to contact tracker I finally got a hold of them on 26 October 2017 to query why I am being charged on a system for a vehicle that I do not own anymore. I was told that I cannot be refunded the money for all these months, and to top it off the call center agent tells me that I have to give 1 months notice so they are still going to charge me for the next month as well. I am sure Tracker is doing this for thousands of customers. This is basically ***** as they are charging the customer for something the do not own. The agent still has the never to ask me if I want to fit a tracker in my new car. Really? The agent was so unwilling to even find out if I could get a refund. It's almost R1000 of mince that Tracker has basically ******. I will never use this company's products again and I will never recommend them to anyone either.
