Chase-Sapphire had a promo on Lyft so I downloaded the app and reserved a ride from Home to Airport which is about 27 miles away last May 14. The app says $40 so I continued with the app. During my trip, I checked my account and the charge was $190+. I called Chase and they said they will file the dispute for me. After 1 month, Chase came back and said that the charge was correct. My mistake was that I did not get a screenshot of the $40 charge. I called back Chase and they said that they cannot do anything because I did not have proof. I told them that it is highway robbery and in fact, when I came back on 05/27 I took Uber and the charge was only $48. What can I do?
