How to get rid of this annoying voice mail notification?

[AravindhaSwamy]

I'm using Samsung A50, and I got this really annoying voicemail notification a long time ago and I really can't get rid of it. I can't read any voicemail, I tried clearing the cache too, but this notification keeps coming back again. Could anyone assist me with this?

bro just swipe right on the voicemail notification and turn off notification for the particular app

Nah bro, tried it but doesn't work either. Just like that stupid uninstallable Airtel app in A50

I can't turn off the notification and this is what I get when I click on the voicemail option
