Constant callig, up to 7 times a day with no messages left... can't seem to block them

Caller: Youfoodz

called multiple times and let ring through but never left a message. So denied a called and must of seemed like I picked up and they said they were from youfoodz but didn’t realise I wasn’t on the phone

Never left a message as don't answer phone calls that don't leave a message as my friends or work colleagues know to leave a message

Caller: 0485 934 271

Food box service company

I rang back and it' only rang twice then hung up. So I blocked the number.

I suspect Hellofresh, they tried to call yesterday also but both times left a 1 second voicemail with no message if that makes sense. I made a mistake of providing my phone number on social media for hellofresh free box and soon as I hit submit they just keep calling. Well lesson learned.

Caller: I don’t know

Calls & never leaves a voicemail message… I find this suss!

Calling every day different times a day - constantly

Started receiving calls from this number last week. Never leaves message. Suspected spam.
