Wrongly Invoiced, Multiple Unexplained PreAuthorizations.

Avis wrongly invoiced me and continuously held multiple authorizations against my account that they could not explain. My account was eventually debited into negative with close to Twenty Thousand Rands held up in unjustifiable authorizations. Call them, and they have no idea what's going on. Shame that this has happened whilst my wife is in labor...hospital bill pilling up whilst Avis holds on to my money. AVIS IS TOO BIG FOR CUSTOMER SERVICE, THEY DON'T CARE ABOUT PEOPLE AT ALL.
