Spice Jet Airlines — complaint against spice staff mr tuhin

I m travelling by sg277 from ixa to ccu on[protected]. Mr. Tuhin at the boarding pass desk behaved rudely and tortured mentally without any valid reason. According to him i made a large mistake by not informing him about my baby daughter's age. I then apologise and told me "you must know"!! I again replied i m not aware of that rule sir. Still then he behaved in such way i m in mental agony. He humiliated in front of fellow passengers.
