Online Purchase

Hi I've done an online Purchase on Friday. I received the Online Purchase order number and online Collection form. Now that I phone Makro they tell me that there was an overload on their payment system and that the payment didn't go through. I still have the order number and are willing to pay the amount. Now they tell me that although I have an online order confirmation I can't get the product. I have to order it again and I won't get it at the discounted rate. This was surely a problem on Makro's side. I honestly think that this Black Friday stuff at Makro is just a **** as their systems fail and then you can't purchase. Also if you try and speak to a manager over the phone they keep on dropping the line. Regards, Gerrit
