India Post — Not handover the letter to addresses

Address:

Idukki, Kerala, 685551

I resided in vandanmedu, idukki district, kerala. The post man handling post and courier never visit our premises to handover the post.If its a courier or registered post the customer need to go post office and get the parcel.Before i complaint this to the regional post office, after that that problem solved.But the newly joined postmaster and post man are not customer friendly and even not know basics of customer care. Please advice them to correct themselves and do their duty.
