Deposit missing???

I returned my rental to the O R Tambo branch on 7 Jan 2015 and it's been almost a month of useless phone calls in trying to get my deposit back, which is a large sum of money. In between I have received invoices for extra costs such as E-tolls so clearly their billing department's priorities lie with their own gain and with the attitude of \***** the customer".<br> Eventually Elouise"
