I took a random call without an ID and all I heard over the phone was some abstract sounds that sounded like a children’s playroom, I just asked “what the hell” once it quieted down and then it crescendoed into frenzied laughter(?) before hanging up???
(pic relevant enough for inclusion, fuck it)
The weird noises could be coming from those scammers if there’s some sort of bleed or glitch. I always assumed that if there’s distant crowd noise it means it connected while the rep had their headset down.
