I booked a trip with Viator on 12/29 in route to Milan for a tour on 12/30 that was departing at 7AM. A few hours after my booking around 6PM I received an email from Viator letting me know I needed a Covid Allegen Test no more than 24 hour old or a 48 Hour PCR Test. I told them I had just flew in and by the timeline the tour arrived my Allegen test was less than 48 hours old as I did it at 10:30PM on 1/28. They told me this was not acceptable. I informed them to please cancel and issue a refund as I was not able to get a test before 7AM not only were the lines incredibly long due to a covid crisis at the time in Milan, but all pharmacies were closing soon and there wouldn’t be enough time. They didn't refund because I cancelled within 24 hours well I also booked within 18 hours before the trip. Complete Scam!
