Deposit refund difficulty

After havin purchased 2 high end cars from WBC in a year, we emigrated with R15k in our account at WBC. I contacted customer car who bluntly advised me to visit the branch (which os impossible) and track down the salesman (equally impossible) I find it unfathomable how a seemingly repurable company like WBC gives me the run around in refunding MY cash clearly showing in credit on my online account
