Poor customer experience ??????

I made a payment at Edgar’s active Secunda on the 10 /12/18 I called and advised that they did not receive my payment, I went the store on the 16/12/2018 with the proof of payment. Up to today they are still investigating. I was advise of a 48hours turn around time which is dragging to weeks . Can this problem be resolved before next year assemblies and ensure that the negative effect is also urgently rectified. Ref ********** 9
