Tech trouble update: LG’s only way of communicating is via phone calls at unpredictable times from unpredictable numbers without the option to call back. The projector repair is therefore still up in the air.
On the other hand, since I had to turn off silencing unknown callers, I have become exposed to the wasteland that is the American phone system. It is like a George Saunders short story: robots, aliens, and the ocasional lifeless middle-aged salesperson. LG, why do you torture your customers?
