Had 2 phonecalls in a span of 40 minutes. A lady and a man. Both had foreign accents. Said they were calling from Visa and Mastercard Security Department asking for my identity.
Told me to "calm down" when I questioned what this all was.

Hung up and blocked the number.

Caller: Female foreign accent

Said she was from security dept of Mastercard and Visa. Terminated call

Caller: Caller had an Indian accent and call sounded it was from Overseas in a call centre.

This caller stated that they were from Mastercard. I closed the phone immediately.
