No order placed for my lenses as requested on 14/10/2017

I went to the Centurion Mall on Wednesday 11/10/2017 to order lenses and found out the store was closed as they were moving. On Thursday I gave them a call to find out whether I can place an order telephonically and they refused. I then went on Saturday and I was told that they couldn't help me as my medical aid was closed and they informed me that they will place an order on Monday (1 6/10/2017) after confirming with my medical aid and issuing an invoice to me for payment. I didn't receive a call yesterday and today (17/10/2017) I called to find out why and they told me nothing was done on Monday. The lady promised that she would call my medical aid and get back to me. At the end of the day, nothing was done so I went to the store around 17:00 and they told me the same story like on Saturday.

I still don't have my lenses ordered & my eyes are struggling. What should I do. I've been promised that they will do it tomorrow. I honestly don't believe that I will ever set foot in the Spec Savers Centurion Mall again after I get my contact lenses. Must I beg before I get helped?
