WesBank not sending Natis papers

Receiving exceptionally poor service from WesBank. I settled my vehicle finance at the beginning of December. Had to pay for them to do change of ownership. Was given a lead time of 5 to 7 days. Followed up last week, they send me a generic email saying it was dispatched to DSV. I call DSV, WesBank created the order but never dispatched my papers. Today I get another generic email saying it was dispatched. I call DSV again, WesBank has cancelled the order with them. Extremely poor service to a customer who still has 2 open accounts with them.
