[Resolved]  Whirlpool India — over cooling of refrigerator

My whirlpool double door refrigerator has problem of over cooling since more than a month.
Local service team changed lot of things in first visit but couldn't resolve the problem. They changed some more parts in 2nd visit but still the problem persists.
Local team seems to be incompetent as they work on trial basis.
Call centers have very poor response. They don't care to contact customer to confirm if the problem is resolved or not. They update the status just on inputs from service center.
I have not seen such kind of process anywhere.
I'm loosing lot of eatables every day due to over cooling.
