Payed R140 000 for a car that was taken away because i was a third party, even though I wanted to change ownership and keep paying

I took over installments from my former partner after she failed to continue after a few months of paying the car. In total, I payed just above R140 000 for +3years. When my partner and I separated she cancelled the contract without my concern (To spite me), I then tried to talk to planet42 to change ownerships and i proceed with payments but they sent through people who claimed to be from "GoBid" to collect the vehicle. They had instructed me that I need to contact planet42 to negotiate a deal but they not responding to any of my emails or calls. The people from GoBid blocked me from contacting them, as I had questions and I needed clarity. Outside the 140k payments I spent close to 30k I spent over 20k in repairs which also made me fall back one month in payments. The car also was not moving for a year while i was paying. Yes I am a third party but I brought them business and was willing to keep paying as I was not far from paying if off. I'm very disappointed as they took advantage of the situation for financials gains.
