You should write them letter thanking them. Someone realized their service is crap despite all their pointless metrics. Moving pharmacists around constantly does nothing to improve service. It only buys the DM more time before being fired.
I'm starting to see this occasionally with the new year. It does not apply universally to an entire PBM or chain. I believe it is only when the plan sponsor (employer) or the individual (for Medicare Part D or Obamacare) chooses a less expensive insurance plan that gives a discount in exchange for only having a restricted or preferred pharmacy network.
