CVS review: Prescription “out of stock”

I have been a long standing patient of this particular pharmacy. It changed over to cvs awhile ago, but recently it has become an absolute nightmare. Not only does the pharmacist act demeaning and sometimes downright rude, when I am getting my prescriptions filled, for many months, on and off, when it comes to the "controlled substances" only, they are out of stock.
The last straw was today. The pharmacist was extremely rude to me, never once offering another location (we have about 15 cvs pharmacies with in our one city), but instead told me, "I will have to wait until thursday 2/4", which puts me over my 30 day, and I would be completely out. But to add to it, he refilled my two other "controlled substances" that all go together on 2/1. He even told me that he had 20 in stock, but refused to give them to me, when I told him I have an appt with my doctor next week to get a script for the last 10. I'm sick to my stomach that it has come to this. This pharmacist is often swearing, yelling, pounding on the desk when frustrated. It's absolutely ridiculous. I am done with him and have switched my scripts to a different cvs (which is way out of the way for me), because I do not want to even see this person anymore.
