Exploited unfamiliarity with the language to upsell expensive insurance

Budget staff at Seattle airport uses some manipulative tactics. First, they ask about the number of people and luggage, then tell you that the car you booked is not available and suggest you upgrade for double the price. After refusing, the staff claim the price includes full insurance and advise you to sign electronically to save time. If you trust them, you may fall for it, as I discovered the next day that they had added duplicate insurance, which cost almost as much as the car rental.

The attitude of Budget in Seattle was quite good. They might have realized we were returning customers through our conversation, so they didn't dare push additional charges.

They did not provide the reserved vehicle and took advantage of our lack of English skills to overcharge us. Even though we refueled the car and confirmed it with the inspection agent, we were still charged an extra $20 for supposedly not refueling it. After complaining to the manager, the receipt was corrected. The manager said we would be refunded, but since it was a credit card authorization, we have to wait for the billing cycle to know if we were really refunded.

Rented a Camry but wanted an AWD and had to pay 140USD for the 7 day rental to upgrade to a larger Mazda CX-90 SUV. To my horror on the 4 day of use the car was unable to open and it took us almost an hour before we could reach the budget service line. In the end budget arranged a mechanic which took 1.5 hours to arrive and we had to rush to the Sea-Tec for my wife's flight via uber. Budget arranged another replacement car at Sea-Tec but it was 100% confusion. The replacement car was not available, and was given a chevrolet sedan which I disagreed given the higher price I paid for the SUV. Took me another 45 min to find a replacement car which was a RAV4. The car had its maintenance light signal on the moment I entered the car but I had no choice little did I regret picking up this car which had wiper issues when I was driving down Whistler mountain on a rainy day. It was extremely dangerous for my entire family who were in the car who feared for their lives the entire journey. I am requesting a full investigation on the poor, unsafe cars on Budget!!!!
