When I dial *99 from my home comcast phone, I get the message "this mailbox is currently unavailable". HELP

Finally after 24 days calling support and trying web chat support and having 2 tech visits, someone from advanced tech support called me and fixed it and a couple other issues in 1/2 hour.    Your chat support and call-in support cost me many, many hours of wasted time this month and didn't fix anything.     Most of the time, the support folks had no idea what they were even talking about.     Fortunately, the final call I received from a woman techie fixed several things.
