Swiggy — swiggy representative was very rude when complained about wrong delivery of order and threatening to gracefully accept order of his choice

Hi
I have placed order on swiggy on feb 10th 2020 at 10 pm. But i got different items delivered when i complained same to swiggy, the swiggy representative named "kaibalya" was very headstrong and gave me impolite responses. When i shared live pictures he himself have placed replacement and order of this choice and was threatening me if i don't collect order my swiggy account will be blocked for cash on delivery payment and will be charged cancellation charges.
He gave me very disturbing responses.
Really disappointed with swiggy and it's representative.
