Delhi Metro Rail Corporation [Dmrc] — bad behavior of mewla maharajpur station rajesh kumar nimble

Dear sir/madam,

This is to inform you that yesterday on 4th dec 2016 monday i had issues recharging my smart card through paytm for rs 500 and rs100 respectively. Each time i recharged the amount was deducted but the error showing as operator down.
I asked for help at your counter and spoke to the station master rajesh kumar nimble and each time he shouted at me rudely and started laughing at me looking into my issue and helplessness.
When he was asked to show his identity card he never displayed me his identity card even and started saying do whatever you can and go ahead and complaint against me.

Is this the way your passengers be treated while travelling through metro?
Is this the way how people will be treated disrespectfully?
Is this a professional and ethical way to come to a solution?
When asked for an email address of dmrc where to report this issue he never helped and neither tried to give me an answer.
Why did he shout at me and started laughing at my issue?

Is there any gentleman at dmrc who can reach this email of mine to your director?

I hope my issue should be taken care of rajesh kumar nimble should be punished and he should apologies for his deed for not doing is duties well.

Please look into my issue and call me back.
