CVS review: Fraud

I gave the pharmacy my insurance card 6 months ago. Then about a month ago when I asked for the total amount I owed they stated $56.00. I tried to stay cool and I asked are you aware that I have insurance with regence blue shield... They said that yes and that was the amount your insurance company quoted us. I stated will you please review on your records of my previous times that I have refilled the same medication and was charged $2.10? After about 15 minutes the tech came back and charged me $2.10. She apologized and I went on my way. I thought then the issue was resolved but they turned around and attempted their best to charge be the full charge for other medications for the next month and like the first time I had to get the pharmacist/store manager involved. They would come up with more excuses why they were charging me full price w/o insurance then likely turning around and billing my insurance company as well. Cvs are not only liars but thieves as well. Never will I set foot in their store again. I decided to go to publix pharmacy moving forward.
