calls but never leaves a message - I tried to call the number back, it doesn't ring, goes straight to a voicemail that says ' hello you've called the wine group, press 1 to have a call back form one of our team or we will try you again in 24 hours' - I have never signed up with any wine group -telesales or scam for sure, have blocked the number

No message is ever left. Must be some telesales person or a scam

Caller says hi "my name" but when he realises it's an answering machine he hangs up, leaving no message. Sounds like tele-sales to me.
