Zipcar failed to notify me about a penalty ticket which was then passed to DEBT COLLECTORS. Which I found out 12 months (!!!) after the incident. I ended up paying c.£300 for the offence I was not even aware of. August 2021: I had a rental with Zipcar. Apparently, had a traffic offence which I was not notified about back then. August 2022: I'm getting a paper letter from a debt collector agency saying I have an outstanding debt of c.£300. It turned out that Zipcar failed to notify me about the penalty ticket back in 2021. Therefore, it was not paid on time and ended up with debt collectors. Which I figured out only in August 2022, 1 year after the incident. Zipcar support was absolutely horrendous. First, they general support were taking ages to connect me to the relevant team (violations), even though I had a hard deadline with the collectors (1 week left) which I emphasised to them several times. And them the violations team showed no interest in and understanding of my situation, even though it was clearly caused by a flaw in their notification procedure. Needless to say, it took us 5-6 email interactions until I finally saw the scanned copy of the actual penalty ticket I had to pay for. CONCLUSION: I have been Zipcar customer for nearly 4 years, using them very often and spreading a good word within my circle. They've now effectively robbed me for £300, and have made me through humiliating experience of having and paying the collectors' debt. The worst of all, they did not even admit any flaws from their side, and showed no respect and compassion. With regret, I'm now closing my account and will make sure my case is known to as many existing users as possible, so that they are aware of what risks they are actually exposed to. I'm happy to provide the debt collectors' enforcement notice and the penalty ticket with dates and all the details upon request.
