I called back number (02) 8292 1305 reached voice mail for a company called Guardian Insurance.

I went on the internet looking for life insurance, had to put in a phone number and an email, it said that the email was needed to send the quote.
But when I clicked to the next page it just said someone would ring me. Which is what I was trying to avoid

this number is blocked and they just keep calling about 20 calls far in last 2 weeks
