The cooking class we booked changed location/venue & time which was no where near what was advertised. The time was originally at 10am and was changed to 5pm and the overall cooking class went from beautiful Amalfi to some guys apartment nearly an hour away from where we were. All these changes were sent to us (through the Viator website) a couple hours before the cooking class. Total bait and switch. The service provider contacted us asked if we wanted to cancel and we agreed and asked for a refund which they said they would make sure was done. Over a week and a half later and we had not seen a refund so we called Viator and was told they would contact the "operator" and get back to us within 24-48 hours. 2 Days later and we called back again, having been put on hold for nearly 2 hours. They said they needed to contact the operator yet again and said it would be 24 - 48 hours. I asked for a supervisor and they hung up on me. We called back yet again and they said they would send an email which we received that said "no refunds" due to Vitaor having paid the tour operator in full. And now we are out $400! We have documented proof through the Viator site that shows that what was changed by the service provider and they don't care that it was changed. Total scam. My credit card company has been contacted to document this and we will report this to the FTC and every other consumer rights protection agency in both the US and EU.
