ABSA vehicle finance

We purchased a double cab Ford Ranger through Absa in 2015 on a 30% residual. Absa contacted us a month ago wanting to repo our vehicle as they say we were in arrears, only to realize that the residual value came in, in 2020. We never received any statements or form of communication in the last 6 years. Now we wanted to purchase another vehicle and no bank is even interested to help, as it shows we are in arrears thus after we agreed to pay the sum of R96 000.00 in a very short period of time ( 6 months ) we have a company that has been with Absa since the beginning, all our staff members and even our personal accounts are with Absa, we are extremely tempted to move all accounts from Absa in the near future.
