What points to the body rather than the trim
Water appearing inside the wall, in a ceiling below, or a handle that turns without changing anything, all point past the trim. None of them are fixed by a new escutcheon.
Why the temperature swings
A valve that is not pressure-balanced sees the cold side drop when something else draws cold water, and the mix at the head follows it. That is the fault anti-scald valves were introduced to remove.

Checking a plumber in Missouri
Missouri has no state plumbing board. Section 341.010 of the Revised Statutes requires a certificate for plumbers working in cities or towns of fifteen thousand or more inhabitants, and the chapter elsewhere recognizes licenses issued by any county or city operating under plumbing rules, so the office that issued one is a local office. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.
