Payless Rental Car Hidden charges, upgrading without informing, and refusing to change charge from one week to two days Seattle Washington

I reserved a car at Payless Rental Car through Hotwire with a weekly charge total of $196.00, but the total estimated charges were over $600. I didn't realize this until the next day, so I returned the car after having it a bit over 48 hours. Upon return, I was informed that my charge would be $442 for those two days. They couldn't print me an itemized receipt because their printer was broken. I asked them why it was so much and they pointed to where they had charged me to upgrade to a luxury vehicle (without telling me - and it wasn't really a luxury vehicle, it was a Mazda 5), and for a Loss Damage Waiver, but the total still didn't make sense. They said they would email me the receipt. I recieved the emailed version, and apparently I was charged for a full week even though I returned it two days later. 

Here are the totals:

Time and Mileage: 236.74 

11.10% Concession Recovery Fee 36.99

CUSTOMER FACILITY CHG 6.00/D 18.00

VEH LICENSE RECOUP 0.60/DY 1.80

ENERGY RECOVERY 0.60/DY 1.80

Optional Services Total Taxable: 17.97

7.7% RENTAL TAX 24.12

Optional Services Total Non Taxable: 74.97 ______________________________________________________________________

Your Total Charges paid: 442.15

All for renting a car on 8/27/16 and returning it 8/29/16

Completely ridiculous!
