HDFC Bank — hdfc bank credit card not received but bill generated

I have applied for hdfc credit card via a agent in february 2020 and so because of lockdown i did not get the card it self and shows return to bank.
So in july they come again and try to deliver the card in my office address without and call or message via blue dart courier service which have their very bad service.
After that recently i got my annual bill of 590 rupees and still i don't know where the card is?
Already send mail and try to connect the care too but no one is answering the agent said that if i merge some policy or dth the card it self free to me life time so i did it same.
Dear hdfc team if you are reading this kindly connect me.
