POOR SERVICE ONLY CARES ABOUT MONEY / PAYMENT

Before the cancellation one of the sales ladies called to inform me that I owe them for what I wasn't even sure of and it was the first time I heard of their name and immediately I told her to cancel the contract that I wasn't aware of it at the beginning as I have my own tracker and everything, well she seemed not to understand the questions I was asking her but instead she was rude, because she was saying I owe them I have an outstanding balance which I have to pay and I kept on telling her that I don't know anything about their company if I knew maybe I would've never looked for something else but when we went deep I ask where did they get my details its then she said from the dealership where I bought the car from and the dealership paid for two years in advance well I asked her then why is it the problem to cancel this contract as you can hear that I'm not interested in your company then she said I will have to pay first before I cancel had to ask her again that she told me my dealership paid for two years in advance but still want me to pay again to cancel the contract then I told her I won't pay they can deduct it from the advance that's already being paid then she ended our call, well mid-February I wrote a formal cancellation email to them and cc my dealership and the cancellation was confirmed and the lady called again to apologies and everything was sorted well end of feb the debit order went off I then wrote an email again asking about the debit order since everything was sorted there was no respond until recently they send me an invoice of R209.12 again remember I've cancelled the contract mid-February the debit order went off on the 28 feb then why are they still sending me invoices and all that because we no longer have a binding agreement. I even told them they knew about me all along, but they've never bothered to check if I needed extra services compared to the one I have now, they check if everything is still ok but for them it was like I have to pay for something I don't know something I don't even use something I didn't even know if it exist something I've never heard of even don't have their contact details because I had no panic buttons no access to see car location I had nothing and knew nothing about them except invoice. so, guys its very wise to look out for this kind of business especially those who only communicate with you when they need your money.
