Landed in JFK at night, rented a car, and experienced aggressive insurance upselling. I had already told the staff that I bought full insurance on the app, but they still handed me several English documents and asked me to sign them. I had my child translate for me, and it turned out to be additional insurance. I refused to sign and reiterated that I had already purchased full insurance. The staff claimed they couldn't see my insurance purchase on their website. I called the car rental customer service for coordination. The customer service confirmed that the staff knew about my insurance. At this point, the staff became very rude, spoke extremely fast, and handed me a toll fee card for signing. The price was outrageous, with a 12-day rental costing $256. I asked if it was the rental fee, deposit, or a bundled fee, fearing a misunderstanding. The staff impatiently said it was the rental fee and asked me to sign. I called customer service again. After a long conversation between the customer service and the staff, and even with the headquarters, they advised me to give up the rental, citing unreasonable charges. Headquarters confirmed there was no such price. The back-and-forth took over an hour. I will never rent from this company again; it's terrible.
