Bad aftercare service

Not very happy with the service I have received in Mar 2023 from this company. I had a repair done in Nov 2022, this was to flush and re-gas the fridge. 3.5 months later Mar 2023 the fridge isn't working again. it needs a new flush and re-gas, and they want me to pay for this again. As such I do not have any trust in the workmanship provided.
