Car track is a ****

I had a contract with car track since 2022 April..my contract which should have been been my last month for one device...the other was going to be on September Along the way I sold the bikes but because I signed a contract I honored and still payed...2024 October I got retrenched could not pay anymore March they started to hand me over to their lawyers, I called n made arrangements to pay with my uif because they told me even if I'm not working it's my responsibility to pay I managed to gather some money initially they said I'm owing R2033 and then it included the cancelation or deactivation fee it amounted to R3186 I payed that whole amount on the of 3186 on the 5 of April 2025 mind due the call to make arrangements was done on the 2and April

Now I call them to request proof of cancelation since I have settled the whole amount The say I can't get that as I'm still going to be billed for the 21days

My question is why should I make an arrangements and ask be given the total outstanding while it will still grow on the side after paying the outstanding amount

It's not my 1st time have such issues with car track they are a ******* the **** us with their contracts I would not recommend it to anyone I will never ever use their services again even on my next units
