A hospital doctor is stranded at his parents' house in Devon, after finding out the train service he has a ticket for does not exist.
The tickets for the Totnes to Paddington Boxing Day service
Pamela Thompson, from Tuckenhay, bought return tickets for her son and his partner over the phone in November.
The couple were due to return to London on the 2002 GMT service from Totnes, but discovered it was not running.
First Great Western has not commented, but National Rail Enquiries confirmed there were no trains until Thursday.
"I'm extremely angry," Mrs Thompson told BBC News.
"My son is a hospital doctor and has to be back as there are always a shortage of doctors around the holidays.
"I bought these tickets in good faith. They've taken the money out of my account, but they haven't notified me that the train's not running now.
"It's spoilt our Boxing Day."
She said First Great Western was not answering any phone calls, while the family has been struggling to find a means of getting the couple back to London.
"I want compensation and I want to speak to someone at First Great Western," she said.
