Reserve Bank Of India [RBI] — rejection of 1 rupee coin.

Address:

Patna, Bihar, 800026

I have almost 25 coins of denomination of 1 ruppee and one of the shopkeeper owner refused to accept my coin. Why these all things are going on...??
Again i insisted the shopkeeper that there in no guidelines of rbi regarding this but he said i can't do anything and i will never accept your 1 ruppee coin not only this he said u can complain anywhere against me...
