CVS review: prescription insurance fraud

CVS employees price gauged by giving me an out of pocket price, when I have insurance. How do I know they aren't putting the script through my insurance after I leave and pay so they can pocket my refund? 1st time I caught it this month: Went to CVS in October 16, 2015 (same pharmacy for 20 years CVS #0295), to pick up a called in prescription for an antibiotic. I arrived at the pharmacy directly after the doctor's office and was charged $54.99. I was sick; I paid. I started to walk away from the register, but my wife walks up and stops me asking for some change to grab necessities, but I had no change from the $55. At that point, I noticed CVS hadn't run the script through my insurance. Same insurance since January 1st. Had to call Insurance company while standing there to force CVS to put through my prescription insurance information. Resulted in a full $54.99 refund because antibiotics are 100% covered. I wouldn't have even noticed because I was sick and just wanted to get out of the store to go home and sleep. How often do you go to the pharmacy in any other condition? 2nd time I caught it this month: Went to the doctor to have blood work results read. Doctor said I need Vitamin D so doctor calls the script in. I receive a call from the CVS pharmacy because they didn't have Vitamin D 50, 000 IU in stock and it would be $16.50. I asked why it wouldn't be covered by my insurance on file...generics $1, brand name $3, antibiotic was 100% covered. CVS employee says Vitamin D2 is a prescription that might be covered, but Vitamin D3 is over the counter so it's not covered. I said no it's 50, 000 IU and the doctor said it's prescription strength. The CVS employee suggests maybe the doctor ordered the wrong script and maybe I should call the doctor. I called the doctor's office and asked that they check the script and let me know what they ordered. Looking at the blood work; they tested Vitamin D3 so I googled Vitamin D2. I learned very few people should ever take Vitamin D2 and it certainly shouldn't have been recommended to save $16. I called a few other pharmacies to find out the price based on my insurance and whether or not the Vitamin D 50, 000 IU is covered and prescription strength. Not only is 50, 000 IU prescription strength, but it's $1 under my insurance. SHOCK! I called my doctor's office back and changed my pharmacy. The nurse says by the way...it was Vitamin D3 we ordered. Another drug I ordered earlier in the year happened to be a script for 10 pills. The pharmacist that I have communicated with at least 15 of the 20 years filled the script and wrung me out for the cost and sent me on my way. I proceeded to leave the store and noticed there were only 8 pills in the bottle; not 10. She says oh I must have mis-counted; I'll fix it. What if I hadn't checked? Next time I'll count my pills before I pay.
