HDFC Bank — Credit card upgradation fraud

Address:

Saltlake sector 1 HDFC bank

Hdfc agents called me and told me there's a new credit card I can upgrade from my old standard hdfc credit card to Regalia card and there will be no monthly no yearly cost and also no renewal charge but when I received that card I see in the terms n conditon it's clearly written 2500 charge annually/renewal, I want to cancel the application and use the old standard credit card I have, but no one is helping from the customer care department .
