The couple were returning from their touring holiday in Santander in Spain, heading back to Portsmouth<\/span>.<\/p>\n Mr Garnett downloaded a number of TV shows on his tablet for the 29-hour journey, planning to spend most of the trip offline.<\/p>\n But the problem arose after he decided to use the internet for 40 minutes, believing he was just the 90-minute free onboard WiFi.<\/p>\n Despite thinking he had connected to the free WiFi, he was actually using the internet on the ship, connecting to the Skybridge\u00a0service after not turning off his data roaming.<\/p>\n This landed him with a whopping \u00a31,862 bill on his return.<\/p>\n Mr Garnett, a seasoned yachtsman who has already sailed around France and the Med, slammed Brittany Ferries for not giving any warning.<\/p>\n He said that neither he nor his wife – who was also hit with a bill of \u00a390 – heard any announcement or given any messages from the ferry operator.<\/p>\n Not only that, but he said they had no problems when sailing from Portsmouth to Bilbao before their trip.<\/p>\n <\/span><\/p>\n <\/span><\/p>\n <\/span><\/p>\n <\/span><\/p>\n However, a spokesperson for Brittany Ferries told the Times that a "clear announcement on the public address system" is given at the start of the sailing, with messages across screens on the ship.<\/p>\n While they apologised for his experience, they said they would not be refunding the bill<\/span>.<\/p>\n Mr Garnett said he was left "horrified and embarrassed," adding: "[My wife] doesn\u2019t normally hold back on criticising me, but she\u2019s actually been pretty sympathetic."<\/p>\n You could still be caught out when travelling by sea, even if your data roaming is turned off.<\/p>\n One woman was charged \u00a311 after someone left two voicemails, despite having her internet off.<\/p>\n Isabel, who was travelling on a cruise, was charged because the voicemail was seen as a call to the location at sea.<\/p>\nRead more on holiday mistakes<\/h2>\n
