Government of India — refuse to take rs 10 coin at petrol pump (station)

Address: Pune, Maharashtra, 413102

When i had gone to fill petrol in by vehicle the salesman at petrol station has refused to take 10 rs coin and said that bank is not accepting the rs.10 coin for depositing cash. So he can not accept. I told call manager but they told that he is not present at that moment and manager has only told to not accept 10 rs coin from customer. So help me out by suggesting right method to handle this case and help other customers for inconvenience faced for petrol pumps
