Arrogant and rude

I hired a car from Woodford on the 03/04/2015, woodford reserved R5000.00 on my card. I returned the car on the 08/04/2015. I then received the billing statement on the same day (08/04/2015) confirming a total of R 4844.84 that's due. On the 14/04/2015 i received communication from my bank that R4844.84 was paid to Woodford, 2 days after my account is now overdrawn by R4844.84 because woodford is still holding on to the R5000.00 they reserved on my card. I spoke to 4 of their service consultants in the last 4 days on telephone number *** and two of the gentleman who answered were rude, arrogant and dis-interested and hanged up on me after putting me on hold for over 30 minutes while i am hearing them laugh and chart in the background, the other two took my details and promised to get back to me after speaking to their superiors, i am still waiting for woodford to get back to me. I have wasted over R350 on airtime , my bank account is in arrears and they still are holding on to the reserved amount amount! my profile with the bank is ruined and woodford does not care!! their customer service team needs training on how to speak and serve customers!!
