Carrier Midea India — Sold a refubrished defective AC

Address:

Burdwan

I bought a carrier 5 star ac and it was a defective product. starting from the first day louver position memory function not working, after 10 days sleep function stopped working, i called the service center guys and they have changed the PCB after that sleep function started working but with this new PCB louver function still did not work. Again i called them up and they are saying again need to change PCB, i have them you just put a new PCB still why it isnt working. and it did not work with the stock pcb also. Now they are saying we will send upgraded pcb which seems very illogical for me, for a single customer why would they upgrade entire PCB. im afraid they are doing some patch work on the PCB and sending me.who knows what else will not work. i want a replacement. please help
