A 77-year-old woman was forced to wait seven hours for an ambulance after suffering a broken hip.
South Western Ambulance Service has apologised for the delay in reaching Margaret Clements, who had a fall at her home in Exmouth on Saturday.
The trust says demand was high due to bad weather and 'a number of serious incidents in the area'.
Mrs Clements' family, who have lodged a formal complaint, say she was left lying on a cold conservatory floor from 9am to 4pm despite several 999 calls.
Her son, Mark Clements, told ITV Westcountry he set off from his home in London back to Exmouth when he heard the news, and arrived before the ambulance.
