Weird phone call [closed]

about a year ago I got a phone call from Africa and when i picked up i could hear weird music in the back, they played in different orders and it just sounded weird it was terrible like they didn’t know how to play. I said hello with no respond back so i hung up. Yesterday i got a weird phone call again but i didn’t pick up. they called a few times and then decided to text me saying that i had to pick up ASAP and that there’s a party. He called me babe like we were dating. Today they decided to keep calling so i picked up and the call was from Sweden (where i live) again no answer so i said hello but no one answered so i hung up.

i’m really confused about what is going on and if somebody have heard of something like this before?
