Don't use wesbank

Don't do private car finance with wesbank. I bought a car half financed... half cash. Wesbank instructed me to pay the cash to them, they pay the seller. They paid the seller the financed amount... almost 24 hrs later they haven't paid my cash deposit to the seller. The seller won't release the vehicle obviously. Wesbank has started charging me interest on the finance amount even though I cannot take possession of the car because they haven't paid the deposit. So I have no car.. no cash and an starting to owe interest!!
