Walmart - Pharmacy

I am very disappointed with this pharmacy. My son's prescription of Risperidone which is his only medication and need to take daily each month we are facing delays and excuses for weeks before dispensing it. They say the doctor and insurance are the fault so I call the hospital and they say they already contacted them again and again. I'm not sure what or where the problem is exactly but should the pharmacy take a positive role instead of waiting for indefinite time ?

Absolutely amazing. The staff here are friendly and helpful. They go above and beyond to make sure their customers get what they need, when they need it. A++
