Continuous calls with no messages left

Answered husband's phone for him today. Caller said his name was Josh from Bupa about health insurance and asked if we had looked at the information he had sent through. He used my name which I had not given so that made me think it might be legitimate but I just said wanted "more time to consider" as he offered that option. Ended the call. Checked the number on Google and came across this platform. Checked with husband, neither of us have contacted Bupa recently.
