No Refunds from Avis

Booked a car from Avis on the 26-30th November 2015. I was told that the money will be back in my account in the next 7 days after the drop-off and today its 7 days. Avis reserved R4091.83 from my cheque account.<br> I called Avis on the 3rd Dec 2015 and i was told its still within 7 days so its probably still being processed.<br> Called back today as my money is still not in my account and i was told the matter will be escalated to Nedbank to communicate with my bank (FNB) to find out why the money has not been released and this will take 2 working days. I had plans for MY money and this is such an inconvenience for me.<br> Can this be escalated ASAP and as SLA has been breached and can i have MY money asap not in the next 2 working days. <br>
