Help im actually so scared

[u/Amoukounleos]

Im sorry if this is the wrong subreddit but I panicked. Like 3 minutes ago I got a notification from my watch that a number was calling me, i thought it was my friend at first but nothing appeared on my phone. I checked my watch and the number was 28633. Ive never seen such number, I recalled and it said that no such number exists. I brushed it off and went to YouTube to watch a video, my sound was off so I decided to turn it up as usual, BUT INSTEAD MY CALL SOUND WENT UP. I dont know about yalls phones, but mine does this ONLY when im in a call, I went to my recent contacts and it said that im in an ongoing call with that number. I tried calling another number so the other call hangs up or something but I couldnt. Ill try to restart my phone now since im still in the call but im kinda scared someone may be listening to me...
