Why would a surgery you're not registered with call you?

So I got a strange voice message. It sounds a bit suspicious to me because of that same background noise you get from a phone sales person. But their claiming to be a surgery I think from what I can gather anyway. Sound quality is really bad and you can't understand it at all. I'm just putting it down to a miss dialed number 🤷 to someone with a similar name to me 🤷. Not the first time it's happened too! 😂
