Outward Trip Barcelona to Cruise Port May 2022. Vehicle was very late, no contact. Tried to ring emergency number supplied which was a recorded message in Spanish even though I had rang the UK number. Vehicle eventually arrived just as we were getting into a local taxi. Inward trip from Cruise Port to Barcelona Airport vehicle did not turn up after 30 minutes. Rang emergency number, operator said she would check and ring me back. She did and told me the driver was at the port gates and would be there in 10 minutes. 15 minutes later she rang to confirm we had been picked up but we hadn't. A few minutes later she rang me to say they could not lift us and to find our own way to airport and claim a refund. I was sent a link to make a report. On return home i completed the report including our taxi receipt but after 30 days I had heard nothing so wrote to them again and they replied to say refund of taxi fare had been credited to my credit card and it appeared a few days later. Although I got my refund I cannot recommend Sun Transfers.
