Metro Railway, Kolkata — Misbehave of metro security staff

Everyday I take metro from Kavi Nazrul metro station to Chandni Chowk. But today I faced a problem
1. When I was entering the security (male) staff called me addressing "hoy Madam" for checking my bag in automatic scanner. At first the tone he talked me is very rough which is not expecting.
2. I told him to check my bag with hand metal detector but he refused to do that, then I request to check the bag manually as in COVID pandemic situation I am not comfortable to put my bag on the same machine where everyone is putting their bag. He spoke very roughly with me and forced me to give my bag in that machine.
3. They don't have the facility of sanitizing the bag after checking. In this Covid situation when we all are advised to stay proper distance and sanitization protocol then how we could so irresponsible to put our bag in a machine which is never been sanitized. Even their is no option of sanitize the bag after the checking.
4. They sent me to near ticket counter where only one sanitizer machine was there with few amount of sanitizer. I am a vertigo and panic patient. So it is very difficult for me to walk here and there for checking and sanitizing the bag. Metro staff didn't cooperate me. They always used to sit and give instructions.
5. There are 2 sanitizer machines in all metro station but all remain empty most of the time or written with a not "out of service".
6. There was only one security staff who was watching the queue weather anyone is not putting his or her belongings in the machine but my question is if there is only one staff then who would watch the screen? They are not focused to the screen they are more focused to harass the common men specially women.
7. In chandni station they don't have automatic machine they have hand detector. There they have to work, so there is no checking. I think it is nothing but just n eye wash to show off hoe tough our security is. Where they have to do minimum work they don't check. Where it is harassment then they force to put bag because they don't give to any labour for that.

I don't is it the proper site of lodging a complain or not. My request if it is a proper channel please look into this matter. In covid situation all metro station must have the facility of manual checking/ Hand detector. There is a possibility of spread virus from one's bag to another by putting the bag in the same machine.
