They called once a day for a week, no message left.
I rang the number and got a recording saying that if I was calling about a missed call,this is where it originated and it was for a charity I supported or another charity, and if I did not wish to receive further calls to email (address given very quickly and not clearly) Will try this and see if it works

received call advise not interested requested to OPT out.

I called back number (07) 3606 0841 reached voice mail for a charity but did not say the name.
