The trip started out great, it took a little bit to check in and the staff was friendly and received our Go Car and we were off, our first stop was Fort Point, we walked around for 10 minutes came back and tried starting our car and nothing. I called the number they provided and the gentleman who picked up the phone told me someone would be at my location in 25-30 minutes(mind you, we were only maybe 15 minutes away from their pickup location on Beach Street), no problem, we waited. 45 minutes rolls around and no one has come with my replacement car. I called back and was told by the same gentleman that there was backup and the replacement car should be there in 15 minutes, 25 minutes goes by and I called back again. They apologized and told me the replacement car should be there in 15 minutes. By this point, we had been at Fort Point for about 2 hours!! I was done, we had to take an Uber back to their main location and I asked for a refund. This was unacceptable, and the fact that I kept having to call them and ask if someone was still on their way was very annoying. Very disappointed in this service and won’t try them again. Next time we want to tour the city, we’ll just use the Big Bus Tour, never have had an issue with them.
