I called back number (07) 3547 7107 reached voice mail for a charity company but did not say the name.

Caller: 07 3547 7107

Got a call from this number... they told me they are from green peace and asked for my card number for donation

Ih ave had this call twice in two days and as soon as I answer they hang up

Had two calls from this number one after the other, didn't answer as I assumed it was a spam call. Number blocked

its surf life savers, who have been asked numerous times to NOT call me. apparently they want legal action..who knew!

Called twice in quick succession..I blocked as I have had them hang up when I answered yesterday.
Strangely within 5 minutes I had 2 more calls from an almost identical number. Only the last digit was a 3.

This is the 3rd call in 3 days from 3 very similar numbers. Looking up detail on the other 2 informed me they were unwanted callers, and I blocked both of those. So they tried a new number.
