Appalling service

my wife bought a phone months ago on the 20July 2020 and it was returned on the 30th of September because it was malfunctional, it did not charge there after wouldn't switch on, and they said the were booking it for repairs on the 30th September till date nothing was said. I am coming today for my money no stories and for the inconvenience i have to be reimbursed in full no stories otherwise i am taking it up to the ombudsman.
