Missing online order

I wanted to make an online purchase during the Cyber Monday Sale, i loaded my shopping cart before 4 in the morning and i was ready to checkout using my edgars card and to my horror i was told i had no credit which was untrue, so i decided to wait till the call centre opened so they could check for me what happened to my card. They checked for me and they informed me i had enough credit. I tried to checkout and the system bombed out. I decided to use my debit card and i still couldn't check out. Then at some point i was put on some ridiculous queue for hours and hours and still couldn't check out. So i decided to do a test and i bought two items as GUEST and not a Edcon online profile shopper and to my surprise the transaction went through. The issue i am experiencing is that i cannot locate that order as i didn't get a confirmation email, i have called several times since Tuesday and sent my bank statement till today noone can tell me where that order is and what my order number is?. Edgars needs to tell me what happened to my order or they must give me a refund. The online website is pathethic its sad, i believe their IT department needs to go back to the drawing board and fix that site because this high level of inefficiency is unacceptable.
