Interaction with Alpha Vantage?

I'm not so sure.  I haven't noticed any problems in their data (though I haven't done extensive testing), but in my opinion it is a bad sign if there's no way to contact them.

e.g. 2004-11-01

GS['2004-10-28/2004-11-03','Low']

              Low
2004-10-28 95.80
2004-10-29 97.43
2004-11-01  9.12
2004-11-02 98.50
2004-11-03 98.68

Did you try reporting that to Alpha Vantage?  That's the kind of thing 
they did respond to on Aug 17 (see 
https://github.com/joshuaulrich/quantmod/issues/176).

Now that I read those messages more closely, it does appear they were in 
touch with anozari sometime in July.  So perhaps it's just me they don't 
respond to.  I was asking how to do things (and suggesting documentation 
and metadata additions), I wasn't reporting on data errors.
