Received a call from this unknown number. Didn't leave a message. Call ended before I could answer. From previous comments its an organisation on behalf of a charity.
I have my favourite charities so don't bother calling me. Number is now Blocked.

Don’t even bother

Calls at around 7pm every second or third evening!! Not a number known to me so I don't answer. No message left.

Had this number call me at least 3 times a week for last 2-3 weeks w no message left.

Yet another scammer phoned I answered and nothing from their end and then they hung up.....so over all these scam callers

This number is already blocked on my phone, but that hasn't stopped them trying to call me for the last 4 working days in a row!
