Disappointing services Dischem Wynberg

I used Wynberg Surgical pharmacy for many years, and was never disappointed with their service. Then Dischem took over. I also had no problem with their service until today. In later years I received my chronic meds from them. Every script is for six months medication. I never knew that I will be penalised for having a script and not giving it to them immediately. I went for my six month visit to my GP. He then said that my prescription is due at the end of the following month, and that he will give it to me. Then I don't have to come back the following month for a script. I thought that it was a great idea. However, Dischem WYNBERG decided to remove one (of two) legally prescribed chronic medicine from the script because I did not bring it in immediately. This, even though I did not require it until the following month. Now, I must pay for a script or another visit to my GP, or skip that medication for one month. Anyway, I think that it is time to move on to another pharmacy.
