Charged twice for car rental

I rented a vehicle from Budget Car Hire on the 1st of October 2014 for three months. When I dropped off the vehicle everything was in order and paid in full. <br> <br> ... Or so I thought. Then, on the 26th of March 2015 I noticed a debit from my account for the amount of R15 797 from Bidvest Car Rental. I phoned immediately Budget only to learn that they changed their name to Bidvest. The manager at the Phalaborwa branch was very slow off the mark to help me and after dealing with him and then the regional manager in Hoedspruit I ended up dealing directly with the accounts department at their head office. What was to follow was an absolute joke. I got passed around with repeated \get back to you tomorrow"and \"" we are looking into it\"". All the while I was waiting for money to show up again. It must be noted as well that my wife was a month away from giving birth! Eventually after many months I got most of the money back in dribs and drabs - \""a technical error\"" was their excuse. And that was that. Just a curt \""sorry\"". Bidvest did nothing in return. I own a lodge and my guests use rental cars by the hundreds and I will never send them Bidvest's way. Very poor management and recourse. """
