Horrible Service

I went to a clicks store in Vincent Park mall today and arrived at the store around 17H53. When I got to the door I noticed that the door was closed, I then approached the door as other customers were going out, I then asked the security guard that was at the door if I could go in because I needed to collect my medication. The security guard then told me that the shop is closed and I pointed to him that the trading hours on the shop window says the store closes at 18H00. I pleaded with this guy that I needed to collect my medication that I must take the next morning and as I was busy trying to talk to this security guy he closed the door on my face. What I need to know is how does a big store like Clicks treat people like that? If your trading hours are until 17H50 then put the right information on your shop windows and stop misleading people! I needed to collect my medication and I couldn't. Yet I got to your shop before closing time. I need feedback on this matter. My health could be compromised because of your wrong information/ trading times and horrible customer service. I don't think I will ever take my repeat prescriptions to clicks because of how I was treated today. You have lost a valuable customer in me!
