Phoenix Car Rental Quoted me $278.00 for two day car rental with a $500 deposit and charged me $412.00. Phoenix Arizona

I had needed to rent a car without using a credit card (debit card only), so I called around and when I called Phoenix Car Rentals, they quoted me a $278.00 total rental amount for two days, with a $500 dollar deposit. So, I went and rented the vehicle, which was not in the best condition and the person behind the counter was in a hurry, he copied my driver's license and debit card on a copier and in a rushed manner without explaining anything, agreed verbally when I asked that the total amount for two days was $278.00, he said "yes, its $278.00 for two days". The time was 15 minutes to 6pm and he said they were closing at 6pm. So being rushed and having him verbally agree to the amount, I didn't think twice to look at the paperwork before initialing it. It was not until I recieved the refund back onto my account, did I notice that only $88.00 was refunded. I called them back and asked how come they only refunded this amount, instead of the difference of $500.00, minus $278.00. The person told me to look at my copy of the agreement and it was then that I noticed that the amount was $412.00. These guys are tricky and deceptive, please do not let this happen to you.
