Hisense fridge - utterly disappointed in the quality of their product

I bought an Hisense fridge from hirsch and a day before the warranty expired the fridge stopped working. The technician comes out and advised after a minute of inspecting the fridge that the pc board is damaged due to roaches. I asked him to check the compressor as my own technician is stating that the compressor is not working but Hisense technician is saying that it's the pc board without checking the compressor or anything further. I asked him to state how roaches damaged the pc board without any wires being damaged and he said it happens. To me it's odd that a day before the warranty expires my fridge stops working. It was not a cheap or second hand fridge and I bought it from Hirsch and this is what I get within 5 years. I believe that Hisense products is not manufactured to last long and when it does give up then they look for all possible reasons not to fix the problem. Frustrated and annoyed and I will never purchase any other Hisense product again
