CVS Pharmacy complaint: Medication not being filled

The genius of CVS prevails again. I have a very hard time having a specific medication refilled at this pharmacy. 3 months in a row which cooincides with the round robins shake up of pharmacy personal. For the past 3 months, the pharmacy has been up to 6 days late filling this prescription. I called the pharmacy and am told the doctors office has not submitted a refill authorization. I talk to the doctors nusrse who tells me the authorization was submitted to CVS 6 days before before being told by CVS personal that it was not submitted. 3 TIMES IN A ROW. In the past, I would request a refill from my doctors office, and they would submit the request to CVS. I normally requested the reill a few days before the medication can be refilled. I would get a notice via txt instructing me that my medication was to soon to refill. Of course I knew this but was happing in the knowledge that I knew CVS had the prescription ON HOLD. NOW I DON’T RECIEVE ANY NOTICE. The pharmacist flat out lied to me last month telling me she never received a prescription from my doctors office. I contacted my doctors office who refuted this claim telling me they submitted the prescription a week earlier.
