CVS review: Medication (pills)

Hello!
Two times within 6 months the pharmacy department at CVS at Rt.146 in Clifton park, NY got my prescription wrong. The count of the pills was completely off. In May of 2019 instead of 60 pills (yea, I know a lot) they gave me 25. It's not just 5 or 10 short, it's like 40 off!. When I called nobody apologized, just said come over we will give you the rest (what if I am 90 y.o. lady who can't do it). I was shocked. It took me 4 days to get to the manager and discussed this.
This week in December it happened again. Instead of 24 pills they gave me 14. The same happened again. "Come over we will give you the rest". Now I wasn't sure that they got my prescription right. One time is a mistake, two times it's a pattern. When I talked to the manager she said they have so many prescriptions to fill, they are still doing a good job!
As I understood her right, "who cares if we made a dozen or 2 dozens mistakes, we have so much volume and that's why we STILL do a good job."
Now I am afraid that somebody is stealing pills, and my insurance pays for that.
