A north Queensland resident says she believes her mother would still be alive if there had not been a major failure of the Telstra network.
Anne-Marie Rankmore found her 75-year-old mother unconscious on the floor of her Proserpine home next to a phone and a home alert button during the Australia Day long weekend.
She later died in hospital.
The Telstra triple zero network was not working at the time, due to storm and flood damage to lines.
Ms Rankmore says it is unacceptable.
"My family is just a total wreck - I have to be the stronger one," she said.
"I mean I ring my mum three or four times a day every day I've done that all my life since I've left home.
"Even when my phone rings you know I think it's mum.
"I do blame them."
She says she has tried several times to contact Telstra about the incident.
"I got an email back from them saying they'll reply back in five days - that was last Wednesday, five days from there," she said.
"Then I rung them on the Monday just gone, my mum was cremated on that Monday.
"I was on the phone to them for an hour, they kept passing me through to people and then they had to find a case manager.
"Then they said they'd get back to me by the end of the week."
In a statement, Telstra says it is trying to contact the family as a matter of priority.
