Dis-Chem Menlyn dispenses wrong medication - beware!

I give it a one star as I'm not allowed to give zero. Dis-Chem Menlyn pharmacists reached a new level of incompetence. I went later yesterday to get my daughters prescription. As I got home late I just put it down, opened it up this morning. The pharmacists gave me the wrong medication. Wow is this even legal? So with the wrong medication, my medical aid will be charged with the wrong things, I have to go back and get the right things and and causing me additional inconvenience. Can someone please help? I hope the owner will start hiring competent people and not the dump unfriendly and useless staff he currently is sitting with. I want this resolved asap.
