Unfairly cancelled order with unresolved ebucks issue

Ordered an item on special from the company. tried to make partial payment via ebucks and my credit card.... The ebucks came off my account and was expecting to pay the rest the amount with my card. Unfortunately the ebucks deduction amount failed to reflect on the purchase price and was thus forcing me to pay full price using my credit card. I therefore contacted takealot immediatedly making them aware of the issue. the matter was escalated via email but no response occured after that. While waiting on the response and the ebucks payment to reflect so i could finishing paying the order they just cancelled my order before the ebucks issue was resolved and now refuse to honour the initial purchase.....How was i suppose to complete purchase if they failed to resolve the ebucks issue or even respond to the escalated email.... totally inept service....
