Whether you're dealing with these folks as Economybookings.com or Bookinggroup.com, do not hit 'enter', 'confirm', 'pay now', or anything remotely resmbling a commitment to give them ANY of your money.
I've been double-charged by them and Fox Rent a Car for a 4-day rental. I was initially quoted $18/day. It was indeed too good to be true. Almost $400 later in combined charges, most of which have been explained away as 'fees', I'm now stuck in the Customer Service abyss, with my inquiries ultimately just being ignored. I was charged 2 late fees, even though I returned the car an hour before my reserved return time. I've spoken and emailed with Fox at least 3 separate times each, and each time I'm deflected back to Economy bookings, saying the problem was my agreement with them. All Economy has done is forward the emails I've been sending their way on to Fox, and failing to respond directly.
I have been after them for over 2 months and 10 days now for a response, and I'm getting nothing. After taxes, my agreed total payment was just shy of $125. I've been overcharged by more than 100%.
