Kroger review: pharmac

My daughter receive the Dexcom D-6 on April 9, 2019 and did not receive the sensors. was told by a tech there was no prescription. today called the dr. office was told the prescription was sent on 3-14-19. Pharmacist told me it need two authorization. Why did the Pharmacist or tech not communicate this information to her at the time of pick up.
This is the second mess up in two week with a diabetic meds.
This department needs to be fixed before someone is injured or dies from their neglect.
