Worst Service experience

Absolutely the worst service ever experienced with these guys, my medical aid forced me to use them to deliver my wife and I chronic medicine, we had hassles from the beginning to get our medicine delivered, every month it only gets delivered after I followed up with them, now this month again, a week late with life threatening medicines. Surprise the most important one not included in the delivery which is already a week late, been trying the whole morning to get somebody in a senior position to speak to, no luck, not available and will call me. Hope nobody with life threatening meds have to use them. I rate them as a minus 100 - to be experiencing the worst service in SA is really pathetic
