My Online Prepaid Conformation Number 02934974US0 which I prepaid $332.03 for 3 Days. Sales agent Quintin at the Ontario Location stated even though I prepaid my reservation online before arriving at Ontario that I wouldn't be charged anything until I drop the car off at the Reid Airport (Formerly Mc Carran) in Las Vegas. Sales agent Diane at the Reid Airport was extremely rude to me, issued me a new Rental Agreement Number 372833020 stated what Quintin stated wasn't true and proceeded to charge me $280.68 .So lets reiterate: I originally reserved the car for 3 days and only used it for 2 days, ( Picked Up Jan 30th, 2022 @ 11:14 am at Ontario Airport Returned Jan 31st 2022 @ 5:42 pm ). I was charged twice,1st on Jan 30st $250.00 Amex ending 1007 , 2nd on Jan 31st $332.03 Master card ending 3341 and again I only rented the car for 2 days, not 3 days and I've been charged a grand total of $ 582.03 for just 2 days. Clearly I'm not satisfied with the Budget customer service I received, I was charged twice, overcharged for only 2 days, and talked to in an extremely rude manner by Diane at the Reid Location (totally unacceptable).
