Never rent a car from Avis.

They charged me a mysterious $661.14 on top of my payment.

After 35 minutes on hold, promising every 30 secs that a CSR would pick up, they hung up on me. Their website says "The rental details are not available at this moment, please try later"

This should be illegal.

@aram fwiw Europcar charged me for 1400 extra km when I returned a car last month, despite me doing no more than 250km in total. I just got an email with a bill attached, and it was immediately charged to my bank card. When I phoned the branch to query it, they said basically "oops, our mistake" and refunded me, but that's only because I noticed, had time to call, and spoke the right language. I shouldn't have to.
@aram also, Wizzair just bumped me off a flight they had oversold, so by law they now have to pay me €250. Their staff gave me a phone number and a web address to claim my money, but the call centre cut me off twice before I found a human being, and the web address gives 404 page not found.
@aram also, Accor hotels last month sent me a confirmation email clearly stating "total cost of your stay: €633" but when I arrived they insisted that was the per-room cost and they wouldn't budge.
@aram I think the common factor here is "corporations that are way too big" where both customers and their staff are but troublesome cogs in a massive machine that doesn't really give a shit about either.
@aram I'm just gonna keep adding to this list. I just reserved a rental car with Enterprise, and I clicked the VIEW/MODIFY RESERVATION button in the confirmation email. I've been staring at this for 25 minutes, and it's made no difference turning off my VPN and trying it in Chrome.

@timsk @aram I had to drive an Avis back to Louisville after many flight cancellations from Chicago and they charged an additional $750 one-way fee.

I hate Avis but forced to use them for work trips. Not my money but still… grr.
