I’m glad I found this website as this number is constantly calling, but ringing once and then hanging up. It must be Greenpeace then for sure as I also recently signed a petition, but I’m pretty sure I didn’t leave my number. I dont do that, for this reason. They must have got if from bullshit metadata somehow. Our identity is not safe anywhere even when you click ‘no’ they still try and get hold of you. I agree with a previous post, spend the bloody donations on actually doing some proper work!!!

2 missed calls and after reading comments I am glad! Greenpeace appear to be the transgresssors as I recently signed one of their petitions. Intend to ask them to unsubscribe me from any future communication by any means.

I have noticed that I'd had a call from this number so decided that maybe I should jump onto 'who called me' and apparently 'after reading the above comments' it's more than likely Greenpeace' kinda glad I missed the call, lol.

I've had several calls from this number over the last few days. I've blocked number, as its gotten extremely annoying.

I've had three calls in the last week from this number... It generally rings 2 or 3 times then stops, leaves no message. I answered it once to see if someone - a human - was there but it again cut so maybe it's voice activated as mentioned above. These calls are bothersome because I don't know who it is or why they are calling. Thank you for the other comments. I see suggested links to Greenpeace.... This is possible as I read and fairly often sign their their emailed petitions, most recently c 23 January re bee-killing pesticides. I've also signed up for The Big Plastic Count an important initiative in March set up by Everyday Plastic and yes Greenpeace.

I've had three calls from this number over the last week or so. My phone had warned me it might be a scam, and they didn't leave it ringing long enough for me to get to the phone, so I didn't know who it was. Now I have read the above comments, I assume it is Greenpeace, as I also signed a petition two weeks ago about stopping dumping of sewage.

Constant calls from green peace after unsubscribing from all contact methods. A real joke

Had 2 phone calls in 2 days which I haven't answered! Coincidentally, I signed a Greenpeace petition a couple of weeks ago about plastic packaging

Noticed I had missed a call from this number. Seems to be something to do with Greenpeace. As with some of the other contributors I had signed an online petition and have no intention of sending monthly donations in the future

I've had 2/3 calls from this number but as I don't speak first it just goes, click, so it must be a voice activated call. Its a pain in the backside

Phone rang, I answered, said hello. no reply within three seconds. This to me is a sign that it's an unwanted call. Used some Anglo Saxon words and hung up. now blocked. :)

Was Greenpeace & as others have said called me following my signing of a petition (about sewage dumping by water companies). Very polite caller & when I said I’d looked up the number on here and wouldn’t be signing up to any direct debit donations she thanked me for my time & asked my preferences for them keeping in touch which was all fine.

I recently signed a petition by Green peace and selected not to be contacted. If this is Greenpeace I specifically had asked not to be contacted. I have blocked the number.

Not sure who it is but if others comments are correct about it being green peace well I have signed a petition by them and if it’s them it’s bit frustrating. I didn’t sign it to be called or asked for Money.

Looks like the number I've just blocked is yet another Greenpeace one, going by previous comments.

This number and 01603851262 have called me 8 times during past 7 days...If this is Greenpeace their time would be better spent elsewhere, fed up with nuisance calls
