Pathetic after sales service

I bought a defy fridge from Hirsch in june. A week later I called to say that the freezer section was not working as it should.A tecnician from Defy was sent and reset the freezer settings. He said to see how it goes and that if we are still not satisfied we can replace the fridge within 6 months. A month later we called Defy to let them know that we still have the same situation with the fridge. Another technician was sent but left with no feedback from defy. I called on numerous occasions and left messages but no one calls back.We've had 3 tecnicians come home, during covid,still no feedback. I Called Hirsch, Nishka said she will email Defy and call us back.That was a week ago. I am still waiting.I have been patient but now five months later i am utterly disappointed at the after sales service I am receiving. Sales persons should have integrity by keeping to the promises they make when they sell you a product.. In my case i was promised that if we ever have a problem,she will resolve it.I want my fridge replaced or my money refunded.
