No account variant cannot help u in this case especially in hdfc
If u r primary account holder this may work but varies from person to person
I'd suggest u directly req them to inc limit and upgrade ur card
Keep ur classic account(assuming u have) no need to upgrade for cc offers
Ur negotiation skills with grievance team matters more than account variant
If u want to upgrade u can but IMO it's just a tag to make the customers feel they r special but there's nothing special except direct call, some locker discounts and free IMPS and high cash transac limit of 5L monthly free in branches
