NO Communication Vehicle FINANCE

I have a vehicle finance with Standard Bank and lost my job in year 2019. As a result I was not able to make payment and requested a payment adjust plan. My account was in arrears post Covid-19 which I had been making payments. To my surprise I have received a call today from a third party on behalf of Standard Bank saying they received an instruction from the bank to keep my vehicle for safe keeping. The guy Ayanda was rushing me on the phone and refused to listen. During lockdown I was not working and therefore was not able to make payment however this month of June we have went back to work and will be able to make payment. Standard Bank did not inform me of any process and the third party had agreed to my arrangement that I will make payment in June. This is frustrating and no communication was sent to me
