My big fat Greek taxi bamboozle here! Checked out...

My big fat Greek taxi bamboozle here! Checked out on June 18th, 2018, and my husband settled up the bill with the front desk and then we left to wait for our taxi out front. Unbeknownst to us, the hotel--after we settled up and checked out--added an additional 48 Euro charge for the taxi, which we did NOT authorize. We are both high level Hilton Honors members and are appalled at this! We caught our taxi, paid the guy in cash, like we do all taxi drivers, and flew home. Then, a nice little additional charge ends up on our AMEX after we checked out and after we paid our taxi driver--the HOTEL charged us for the taxi too!!!! Hmmm, still waiting for a refund, still waiting for Hilton to address this issue we reported...seems like some kind of scam. But, we'll update this review AFTER this gets resolved. And it BETTER get resolved quickly.
