An inquiry has begun after an elderly woman was left on the floor for almost an hour by a carer following a fall.
The 76-year-old woman, from Wiltshire, needs home visits after losing mobility due to a broken hip.
The woman's 82-year-old husband called members of his family for help but the care worker left for another appointment before they arrived.
Enara Complete Care, the care worker's employer, apologised and Wiltshire Council said it was investigating.
The authority said it took the complaint "very seriously" but said the care worker had returned after 20 minutes.
"An investigation will immediately be carried out to find out if the level of care in this case falls below the standards expected from Enara Complete Care," the council spokesman said.
"Wiltshire Council, as the commissioning organisation, will not tolerate poor standards of care from its providers."
Enara Complete Care runs live-at-home care services in the west of Wiltshire on behalf of the county council.
Andy Dun, the firm's chief executive, said the care worker had said the woman fell while using a walking frame.'Very upset'
"When she couldn't get up she offered to call the paramedics so that [the woman] could be assessed and then mobilised.
"The mother and father declined that we should call the paramedics and that she should call the daughter, which we did."
But the woman's daughter Sarah, who does not want to be fully identified, denied the carer had offered to call a paramedic and claimed her mother had been "dropped".
Sarah said her mother was "very upset" by the "dreadful" incident, in which she was left on the floor for nearly an hour.
The woman lives at home near Calne with her husband, who was unable to lift her up and had to telephone for help.
"My mum was lying on the bedroom floor, on her own," Sarah told the BBC.
"The carer had left to go to see to someone else and just left my mum on the floor.
"She put a blanket over her and told my father that she would come back later on.
"Obviously that is not acceptable - that is dreadful."
Sarah added the care worker should have got help after her mother was dropped on the floor.
"These girls should be trained to know that you do not leave somebody," she said.
"We probably should have called a paramedic out to help, but just seeing her like it we couldn't leave her like it."
