My mother needs Xanax, dropped off prescription to walmart pharmacy and picked up next day since it was an hours wait.

the number of pills were to be 60, but there were only 36 in the bottle. I called the pharmacy, asked for a manager. He said he checked all the xanax and it was accounted for. They obviously have an employee stealing them, but he said he would call my dr. to get the missing 24 pills. Of course my doctor said it was not responsible for walmarts errors and since it was a controlled substance, we were out of luck for another month.
He also said the person filling the script was an intern. I suggested they keep a close eye on them.

Dr won't fill either, but there is obviously a problem with someone in the pharmacy. Who do I file a complaint to? The DEA? My mother lost her prescription for meds, so I switched to walmart because all her meds are cheaper there. That being said if you GET the correct number. Who can I complain to as I'm not going to let this be resolved by walmart since they obviously have a drug addict working for them.
