Walmart

This is regarding my visit today 11-22-2021 to the Chino, California store visiting the pharmacy. In July of 2021 I took a valid prescription for my pain medication to this pharmacy. I was told they didn't have the medication in stock. Let me remind you I have been getting it filled here for 3 years. Today I was told that this pain medication wouldn't be prescribed for my medical condition. How do your pharmacists think they have the right to humiliate people and override a doctors prescription. And if there was any question about my prescription why didn't they contact my doctor? I was treated like a low life drug addict when there was no reason for this. Who are they to treat loyal customers like this ? I would like to see something gets done about this matter.
