Standard Chartered Bank — trfd charged on unused credit card

Address:

400064

I availed for a manhattan credit card in nov 2018, hoever made no transcation till date. I as charged inr 1k for subscription fee, i paid off. Later i was charged late fee inr 500 on payment of the earlier subscription fee and again paid off.
Now i am charged inr 18 twice for trfd in feb 2019, i paid it off once and i am charge again.
Are you guys serious that if i have a credit card and not using it, you will still charge me for holding one?
