Poor follow up by Edgars accounts department

I paid R 700 with my master card towards my account at Clearwater mall on the 4th February 2019. this is not reflected on my Edgars statement. I only realised this when I started receiving calls for non payment with the persistent tone that I do owe them money and that I will be black listed if I do not make urgent payment. I have sent copies of my bank statement as proof of payment twice and have now eventually been informed via email that it has been escalated to the relevant store. Yippeeee !! Maybe one day I will get an answer too................
