I rented a car with Thrifty and according to my receipt, the rate increased AFTER my contract was signed. 1/16/21 • Arrived at HNL (Honolulu Airport) • Picked up prepaid rental (paid $147.13 on Expedia) at Thrifty on North Nimitz Hwy • Prepaid contract was for 1/16 - 1/23. 1/23/21 • I exchanged the car at Thrifty with a new reservation until 3/8/21 • Contract rate $100/week, $13.99/extra day, estimated charges $1216.58 3/8/21 • I contacted Thrifty to extend reservation until 3/17/21 • I was assured that rate would be extended as well ($100/week, $13.99/day) 3/17/21 • Car was returned, was told final receipt is available on-line • My card was charged $4173.18 • Rate increased from $100/week to $460/week, $13.99/day to $74/day AFTER I returned the car I have stayed on hold with thrifty many times for over 40 minutes. The two times I was actually connected to an agent, I was disconnected after I was told that they are "looking into it". I have contacted Thrifty 5 times via their website and have received no answer. I have a PDF of all supporting documentation. I have filed a dispute with my credit card company. I have filed a complaint with BBB. I am at a loss as to how to proceed. Thank you
