I was called. They asked if I was "NAME". I answered, "Yes, why?" And they hung up on me. I phoned back, and another person picked up and said, "Hello," once I also said "Hello", they hung up on me again. In the background, I could hear noises resembling a call centre. Both times, the voices had accents from the Indian subcontinent.
