Disgusting service

On the 8th of November 2015 I purchased over R2000 clothes at Edgars and at the same time paid R500 to my account, to my surprise a debit for my account at the end of Nov did not go off so I phoned in to the Call centre on the 2nd of December 2015 to be told that because I paid R500 on the 8th of Nov, my account was up to date and the next debit will be the end of December 2015. So... I go Christmas shopping on the 24th of Dec 2015 and try use my Edgars account... well I couldn't because it was blocked due to non payment?! Really?! That isn't what I was told!! I had to endure complete embarrassment in CNA when I was told my account was blocked and was not able to use my account to purchase Christmas gifts! The fact that a debit did not go off was a worry and so that is why I phoned in, I have No clue if I was just given the wrong information or if my account was up to date and blocked by mistake. I would like this to be rectified ASAP and I can assure you that in future I will not be using my Edgars account!!
