First Flight Couriers — Returned my product without any call/intimation

Address:

Chennai, Tamil Nadu

MY consigment number is B991B1646899. Iam working at ascendas it park chennai. I found the status as "Refused at security gate." Through customer care I somehow got to know the location where it is pending and i called up the person and he is behaving very rude. I asked him you could have called me so that i would have came outside to collect it but he says we can not call you and inform to get the product.That too he has tried twice it seems within 3 days time. When i asked him he says sir we cant deliver/call you and product will be returned. I am really dissappointed the way he speaks to me and the way courier works.
