CVS review: Pharmacy medication

For more than 14 years I've been on the same prescription medication from the same doctor using CVS Pharmacy. The last few years CVS for some reason cannot keep this medication in stock. Same medication 14 years every month they know I'm coming why won't they keep this in stock? Putting my health at risk! Causing my insurance to fall back. When speaking to the pharmacist about this he always tells me to take my business somewhere else very disrespectful. This is not something new this has been going on for months and very much needs to be addressed! They're dealing with my health it's sad when a pharmacy rewrites the prescriptions the doctor writes. On occasion I would only get partial prescriptions filled CVS must do better my next step will be legal actions! CVS must be held accountable! Oxycodone 30/120
