State Bank Of India [SBI] — misbehave of manager

Address:

park street 12 b kolkata 700071, 700071

I am raju naskar working in bsnl as junior accounts officer, we have a corporate account in park street branch (Br. Code - 000150). Everyday i went bank regularly for depositing cheque approx amount 200 per day because bank newlly introduce a machine for cheque remittance, they stoped manually receiving.
As usual today i also went to bank for cheque remittance but the machine was not working and we have to deposit lots of cheques. One official was with me, he curiously asked the chief manager (Santosh sah) when will the problem solve? That time i was not along with him and the matter was totally unknown. Suddenly the manager came to me and told me some unpleasant word like "you dont have any knowledge, i can't take the cheques, will i take the cheques in my mouth then put the cheques in my mouth, we will not receive any cheques please transfer your account, etc, etc."' there was a huge crowd coz yesterday's bank strike and manager was shouting on me like a # person i am. I feel very much insult. I know he is facing lots of pressure but he has understand that he is a chief manager and he has to face pressure.
Is this sbi's customer policy to facing customer, if it was done by normal staff it can be tolerable but if it was done by the chief manager then it is not acceptable.
