Trying to sell health insurance

Caller: Next Gen

Woman calling from Next Gen collecting clients for Compare the Market. Wanted details so that she could get Compare the Market to call me regarding no obligation comparison for health insurance. I declined.
The number rang back a few minutes later and again later that day. I have had 6 calls from this number in the last two days.

They keep calling me too. I have not called them back.
