Answered question
I removed voicemail from my plan last month but I keep getting a text from fizz that someone tried to leave a voicemail and to erase my msgs. How do I get this to stop?

You can try the way Mike mentionned, but apart from that, there isnt really any other way, I dont even think you can block the Fizz system number. Also seems like a bug, you should let Fizz know so that they can issue a fix for it later on.
You probably still have vm until the end of your pay cycle. Wait and see if it gets resolved after that and contact support if needed.
