Ordered premium channel 2 days ago - still not available

I signed in to Xfinity and ordered Starz 2 days ago.   I got an email saying they had received my order and were "working on it."  That was 2 days ago.  When I try to access Starz I get the message that I must subscribe to watch it.  Last time I did this it took about 15 minutes.  I "chatted" with the chat bot which was no help whatsoever.  Was told to "refresh" which I did with no result.  Any help would be appreciated.  Thanks.
