First time they called, didnt leave a message. Second time, a machine told me there was nothing to worry about but I could speak to an agent if I pressed 1. As I do not know who was calling, I did not press 1.

It sounded like the person calling from this number was talking from the bottom of a swimming pool, I couldn’t understand what they were saying and I ended the call.
