India Post — Deposit by cheque in post office ppf account

Address: Faridabad, Haryana, 121002

Today I went to deposit money in my ppf account at post office sector 16A Faridabad Harayana. by cheque of 55000. Person sitting there Gurvinder refused to accept cheque and says that he only accepts cash. On one side Govt is pushing cashless transaction and people sitting at the counter are not promoting cashless. He even refused to write it on the deposit slip that he don't accept cheque.
