My Question or Issue

My Spotify name is being displayed in all of my devices and even in my friend's devices as a random string of letters and numbers and its been like this for the past 2 weeks, and until now I haven't received a good response on how to fix this.

That's actually a very cool name

How do you pronounce it?
