Hi and Welcome to the Community!!
Please try to understand that site is a volunteer-contributed user-to-user community; it has nothing whatsoever to do with any of your formal support channels. This is part of the Ts and Cs to which everyone agrees when signing up here, and is supported by this banner displayed at the top of nearly every page of the site:
Consequently, the advice given is done so freely and voluntarily by those who wish to help others out as best they can. If the answer does not work for them, then that is a sad thing, but not a "bad" thing...after all, they tried to help as best they could, and we should thank them for that contribution.
As a user-to-user community, our goal here is to provide answers and resources as best we can, but sometimes formal support is required, in which case our goal becomes to provide as clear an understanding as possible as to the root cause of any issue (which often will require asking to perform several diagnostic steps to try and rule in/out various possible causes). If the issue is hardware, then that is incredibly difficult (nearly impossible) to truly diagnose at an internet-distance...after many tests, we can perhaps conclude that the issue is hardware, but a true hardware diagnosis really requires in-hand evaluation by a qualified technician...which may indeed be what those poor souls you mention require.
