It sounds as though purchase inventory and materials storage records are not as rigorous as those applied in a well-run facility. After all, having sorted this out, how would one prevent recurrence?

Easy. Contact the manufacturer directly.

Oh, er, see #3⇓.

Matched bearing sets are typically packaged as a set. If separated, you become the proud owner of a collection of no longer matched angular contact bearings.

These days, most of the major bearing manufacturers produce "universally matched" angular contact bearings. For SKF the suffixes:

  • CA, CB, CC or G for internal clearance
  • GA, GB or GC for preload

As long as you know what is needed by way of preload or internal clearance then you can use any two with the same suffix and safely assume that they are "matched" - so you don't have to shoot your storeman yet nor do you have to order them in pairs, though it helps.
