Wrong prescription repeat

Before going to collect my last repeat on my prescription at Dis-Chem Cresta, I went to the doctor to get a new script, then loaded it on the Dis-Chem App. Went to collect my last repeat and handover the original new script for their records . Only to be told I cannot get my last script. So I said ok, I want one of my 6 repeats from the new one. Then they said what I loaded it stuck on the system. I told them I need my script coz I had just finished my last one and to start new the next day. So they gave my 1 repeat. So instead of 6 they showed 1 of 5. Which means they ****** me of another pack of which I pay for. Dis-Chem are ********. They messed up system ****** me of my last one then stole another off my new script. You are not gaining Dis-Chem - I am still paying for my meds. I will NEVER get my prescriptions from them again.
