Individual — deposit of coins

Address:

Sangrur, Punjab, 148028

I m from sunam distt sangrur pb. I have visited a number of times to get 10 rupee coins deposited at local branch of sbi (Old hshs branch sbop with ifsc stbp0000443) but the cashier/manager and others refuse to get the coins deposited and even ask to through them away. But not given anything in written. I m surpriesed that indian banks are refusing indian currency. Why? Kindly help sir.
