Deposit delays !!

I am currently very dissapointed in the service received from woodford carhire. Everything seemed to run smoothly up until I had to receive my refund on my deposit. At the time of renting the car I paid my deposit via debit card plus the 1 day rental fee the gentleman advised me the refund would take 5 to 7 working days. After 1 days rental I extended the carhire for one day and on the day of the extension my card was charged with an additional amount which I asumed was the additional days rental. I returned the vehicle on time and assumed it was only the fuel charged to be deducted from my deposit.Upon receiving my invoice there was another charge for 2 days carhire and my fuel charge that was being deducted from my deposit. I sent a mail to query this to *** as advised on the mail if I have queries i also sent the mail to the lady that sent me my invoice, maybe I am misunderstanding how the charges work and just want an explaining on all these charges, to this day I have not yet received feedback and this was sent on 28 August. I called in to follow up on friday with regards to my refund as it has been longer than 5 days and to be honest I have other financial responsibilities and my debit orders are coming up. The lady in the accounts department she will get the accounts department to attend to my refund asap, when I followed up this morning a gentleman at the headoffice at or tambo advised that this refund can take up to 14 days and that I can send a mail to customer care to try and get them to refun ot sooner. Unfortunetly I am in no position to wait that long as I might not have a flat anymore by the time my refund is paid. Had I know it would take this long I would have never rented a vehicle with Woodford carhire. Please also take note that everytime I called I had to do it 4-5 times to get through to someone. So in desperation for some customer service I am taking to hello peter and asking you to please attend to my queries
