Bad service from pharmacy at Netcare Garden City Hospital

My daughter was hospitalised 3 weeks ago. When she got discharged, there was medication that the pediatrician prescribed. However, the pharmacy did not have stock. They said they would call us when the medication arrives as the medication will arrive the next day. They did not call. Last week, I decided to physically go to the pharmacy and asked for the medication, as they did not answer the phone after numerous attempts at calling them. The pharmacist on duty was unable to identify what medication was outstanding. After waiting for a while, I asked him to please enquire by the pediatrician or the hospital staff and give me a call when it is ready. I still have not received a call to collect my daughter's medication.
