Good morning I need help with process of repossession of my car I bought a car in 2014 ford Kuga finance by wesbank in 2015 I bought chev utility also finance by wesbank also In 2016 I got call from debt review I join it include this two cars In 2017 June/July I got a call from sheriff that he is on the way to collect the car it was around 18h00 Next day I called wesbank to ask what happening the say the cars were not paid I asked to take over from debt review I paid R10000 July 2017 next month I paid 5500 till November I got a call from wesbank saying I did not pay. December of 2017 I paid the amount of 15000, on the 5th January 2018 I paid 3000, 15th I paid R1000 January month end I went hand back the car ford Kuga to boksburg sheriff. I've asked why not both of them coz they were under debt review. My worry is that I did not receive any of the signing documents, court order documents or anything that's saying I'm owing them. They did not tell me that they have received a car and where it's stored. They auction my car without my knowledge that was in April 16th. The auction date I only received it from my statement that now this year 2021... I received a call from them this passed Friday after I launched a complaint towards the statement I have received from them. I asked the about court order document to collect the car that they repossessed that I'm still paying for it.she saying court order document is not in my profile she will ask the wesbank lawyer about court order documents also on our conversation she promised to send me the letter at show how the sell the amount of auction I send her the prove of payment still for the letter of selling the on the auction
