Blue Dart Express — Manner-less customercare executive

Hi team,
I want to lodge a complaint again one of your customer-care executive I had talked with, My Wef no: [protected].

I had called the cc regarding my package for which i got an sms saying delivery attempted however I didnt get any call for the same, but while explaining my issue your CC executive was so mannerless that he was just not ready to listen my issue but tell me his assumptions and also arguing without knowing the fact.
I just want to raise the concern as from a customer side calling a CC is the only thing to get the problem resolved but if the CC executives will not ready to listen ho a customer will lodge his complain or get the issue resolved?

Hoping for an enquiry and a positive reply.

Regards
