Samsung — my new samsung ecobubble front load washing machine has rat bitten

I Created a service request for the same and a service engineer came to inspect the machine. After his inspection he found a rat bit in the board that too in the transformer alone. But the Service engineer asking me to replace the whole borad. I asked him that why cant we change just the transformer in the board. His answer was We are in rural and we dont have the facility to change this spares. This is what samasung is providing as service?
They can sell the product to rural but asking for service means instead of a simple change they are trying to loot money just by saying Rural. We having two machines with same model and both ahd rat bitten. I dont know how come, Is samsung volutairly putting some flavour or color to attact rates.
