Standard Bank and vehicle finance a nightmare to work with

Standard bank vehicle and asset finance. Trying to sell my car, buyer is going through Standard Bank vehicle and asset finance. What a nightmare, people are so slack, days after I sent documents through they contact me and ask me to send it again, prolonging the whole process with days. We are almost ant the end of the process and now only they want to start doing a contract for the buyer, should have been done days ago.
