Hey there! I can absolutely understand how frustrating multiple notifications can be. I would suggest clearing the cache of your device to see if that helps!
Clear the cache for all apps: Open Settings, then Device Care, and tap Optimize now Clear the cache for an individual app: Open Settings, then Apps, select the app, tap Storage, and then tap Clear cache Clear the app data: After clearing the cache, tap Clear data, then OK
If that doesn't help, the voicemail feature is a carrier feature, so I would suggest reaching out to your carrier!
