Poor customer service

<p>So we hired a vehicle when we got to Cape Town from hertz. We were told that the deposit we gave in will be returned once we return the vehicle. However upon returning the vehicle, they told us it takes a few days as we used a credit card. The car was returned on 25/07/2016. I called again a few days later and was told it takes 7 days. I called again after 7 days and now they say it takes 14 days... so which is it?? And y wasn't I told all this info when I fetched the car??? And who is paying for all the calls I'm making to them?? Terribly annoyed with hertz! </p>
