EconomyBookings.com review: Car rental for 1 month

This is the biggest scam ever. I booked what I thought was a great deal for a month rental in January for a July 25 rental. They sent me to America Car Rental (though it seems they also use the name Sonic Car Rental) to pick up my "Suburban or similar", (which turned out to be a Kia, which was the 1st warning sign of future issues coming). When I went to pick up the car, I was forced to purchase "All Insurance" which cost another $1,600. This was after I told them insurance was covered by my platinum AMEX card. They said that was not good. I then told them that I had personal insurance with Chubb which provided coverage far better than they asked for. They then said it had to be with one of 5 companies they listed, all of which are rated lower than Chubb. I had no choice but to pay their extortion as I needed to get the car. I never received a rental agreement but did sign an IPAD which they said acknowledged me picking up the car. When I returned the car they said the car was driven out of state, which I did not dispute. They showed me a rental agreement (which I had never seen before, complete with my electronic signature, presumably prepared from the "acknowledgement" on the IPAD) which indicated it would cost me $500 + $.30 per mile plus an administration fee of $250, all together, they charged an additional $2,400 and I forfeited a $1,000 deposit. I did not receive any information for Economy Bookings until the day before I picked up the car. If I had known of all these restrictions, I would have cancelled everything. I am now out $4 thousand dollars plus the cost of the actual rental. THIS IS A BIG SCAM. I am notifying the state attorney general, the Better Business Bureau, and will be writing similar reviews on all online outlets, including Trust Pilot, YELP, Google, Trip Advisor, Yext, ETC.
