Concern this was a SCAM user who called in an effort to solicit Bank details.

Foreign (perhaps Indian) caller stating they had picked up suspicious charges on my Visa... thus wanted to review my details etc. etc. etc.

The caller refused to answer ANY questions from me, did not credibly ID themselves or provide verification or return contact, became loud, and rude when I asked questions about them and refused to provide any information in reply.

Very concerned this number needs to be investigated, SCAM addressed and blocked.
