Dear sir,

I had gone to sell silver coins in the mentioned branch but they refused to buy the coins from me, though I had purchased the coins from the same branch, but they want me to exchange the coins for other ornaments.
I need cash in exchange.
Kindly help me in this regard
I'll wait for your response...
