Club Factory — social engineering

By social engineering - when i call on customer care no someone recieved the call and when i ask him to check my order details as payment confirmes but order has not placed he asks me about my payment mode and then devit card no and cvv as he said he need to verify my account or else u call on different no i cant help you so i tell him cvv and otp also so then everyone knows my cash got stolen and everytime you call they again ask for cvv to verify it

I know its my mistake but club factory must see this as its not only my mistake
