Daikin Air Conditioners / Daikinindia.com — PCB is useless in jus 1 and half year

Address:

502 Panchvati b wing near s m shetty school powai Mumbai 400072,

We bought ac roughly 2 years back
We chose Daikin as it was promising
After buying this 5 star inverter AC we had less electricity bill but now within no time this machine has stopped cooling the room
Technician from daikin was called and he told us pcb needs either repair or change which will be around 4 to 6k
Now he says der is no definite reason as to y this happens to pcb in our case and this can happen pretty much again
Daikin inverter 5 star AC has thos trouble.
So y is diakin still selling this product if they know it's not compatible
Now wat should I do just keep paying for new pcb every year ? After paying 38500 for this useless ac ? I feel cheated and Daikin looses our trust
