Rbl — Unauthorized credit card charges

Address:

Adajan, Surat, Guajrat, 395009

I have blocked my card but the bank is issuing new credit card again and again without our permission and without demanding any kyc from my side.
I have complaint them 2-3 times through mail and also called them but no one replying. I have visited bajaj finserv branch at universal business hub, lp savani raod, madhuvan circle, surat, gujarat and they replied customer care is not working cause tehy dont have an enough staff available due corona pendamic. I have complaint it from my side and i dont have any requirement for the new card but the bank is issuing new card and charging me for that.
I am requesting you to please see in the matter and solve it as soon as possible.
