Clicks pharmacy sold me expired prescription medication

I am deeply disturbed and will be taking this further. On 8th of April I picked up my monthly prescription of Epileptic medication at Clicks parow center and today I was horrified to see that the drugs had expired on January 2017 a full year ago. This is not disprine or any over the counter medication but a neurological based drug. This is extremely dangerous. Please check the expiry dateon your prescription medication when picking up at clicks Sanlam Centre Parow. I would hate for someone to get hurt as a result of their gross negligence.
