VOICE MAIL NOT WORKING

My phone is a galaxy S24 Ultra.

I am certain the problem is no with my phone . The voice mail need a complete reset from Xfinity. 

 They haven't even tried this.

If it were my phone wouldn't you think

That one of the many Xfinity employees would know that?

 Sorry, I am just incredibly frustrated 

No apologies needed I know you've been working on this for a while, so your frustration is warranted. Can you tell me what happens when you dial out *86 to access your voicemail, and if you receive a message, please let me know what it says?

Ok *86 gets me into my voicemail so I can create my personal greeting. 

That part I  complete, I even go through it to be sure my greeting is available.  When someone calls me they only hear the default female greeting not mine. If they like they leave a message but often because they don't hear my greeting they just hang up.  The only problem I can see an this time is that it just won't  use my greeting.  I have reset thing at the direction of store employees and phone support,  I'm so tired and ready to return it all while I still have time.

 I really like Xfinity but maybe it's not for me 

Thanks for clarifying. So just to confirm, your voicemail is functioning normally outside the voicemail greeting that's left for people calling you?

That's correct , some think it's not important.  My business is very professional and a generic greeting gives the complete opposite impression.   How do we fix it? I need to make a decision soon as the window to leave is closing. Can we get some upper level people to handle this.  I can't  imagine it being difficult.
