Unprofessional consult

Recieved a random call from a lady named Unise this morning from early fruad detection at Nedbank ,she calls says where shes calling from then proceeds to to ask my personal details tp confirm if im infect the client i told her i do not feel comfortable sharing my details if one i did noy request the call or wasnt made aware that such a call will be made.She then replies and says well your card will be blocked and you will have to call in to have it unblocked so i tell her how the hell can she block my card when i didnt request a call pr wasnt informed of such a call taking place later on as a client so she just said well therea nothing she can do they have to block the card and consistently wants to end the call.absolutely disgusting service i too work in a banking industry and we constantly send out sms advising out clients not to share any personal information so what right does this moody Unise lady have to block my card.My husband had a business account with Nedbank but due to this ******* service i will be paying the credit card in full closing the facility and moving his business account Nedbank is absolutely unprofessional
