Some subs can be so dense... So let's simplify this down.
If you place an order for something, or ask for a tech, have one and only one phone number on the account, and fail to answer that phone number or it's bad; YOUR ORDER/TECH IS BEING CANCELED. Done, period, finito; self-inflicted pain by conspiracy theory nutjobs is far too tiring to deal with. You don't have to provide two unique phone numbers, but if you don't, it's your own fault when whatever shipment you order doesn't arrive to you, or the tech leaves. There are 14M+ subs to deal with, in the grand scheme, YOUR account isn't that important. When it becomes an inconvenience, it gets skipped.
Or...put in a second valid phone number. Your choice, and DISH is all about giving choice to subs. Enjoy.
