Refund still not available

I returned a vehicle on the 4th of March - as per booking agreement. Deposit Paid was R4577.80 but my booking was done through [URL Removed] and total due for payment was R1156.00. <br> <br> My second car rental agreement which started on the 4th and ended on the 7 Mar 2016 was a deposit of R2079.80 with original [URL Removed] total due of R952.00<br> <br> Both cars were returned in the exact same condition as I received them, with full tanks of petrol. <br> <br> It is the 09 March 2016 and no refund has been returned to me. Call centre has told me that no invoice was generated. There would have been no way for them to realize this unless I called to ask why funds are not returned to me. <br> <br> According to my calculations I should receive R3421.80 + R1127.80 = R4549.60
