Useless service

The service given by this pharmacy is by far the worst I have ever experienced from any pharmacy. I have been calling for delivery of medication and apart from holding on for 20mins, the excuse remains the same that my delivery details are not on the system. When I ask what they have there it is EXACTLY what it should be. This has happened not once or twice but on multiple occassions. So is it that I must get down on my knees to beg for service and for the medication to be delivered??
