why don’t you call the original repair company back to see what is wrong this time? There is no reason to assume they are dishonest just because something else failed or something went out of adjustment.
It worked for two days so it was trouble shot at least somewhat properly. Calling in someone else would void any warranty the first service company offers, and ALL reputable service companies give warranties on their work.
It doesn’t make sense to just call in someone else without knowing what the first company would do.
