cannot set up VOICE MAIL fairly new Comcast Business Account

Good day 

I am trying to log into the Phone configuration on line and seem to be locked out - or do not have enough in my profile to get through the process.  Now I am locked out - and was on hold for a LONG TIME last week.  Now on HOLD again for way to long.  I need to be able to set up voice mail on the phone ASAP - since I am paying for it.

I have tried to dial *99 from my office phone and it rings busy.  Other posts - state that the VM may not be connected to the phone number correctly - please see about resolving this today - since I am paying for and need to use the VM features.

Thanks

Dean S
