Credit card transaction abroad

Complaining about ABSA is usually futile, but here goes. <br> I paid for a hotel bill overseas on 23 November 2015. There were enough funds in my credit card account, so the transaction should have gone through. It only reflected on my credit card account a week later, by which time the rand had depreciated further against the euro and I was charged more. <br> I have queried this with ABSA but, as usual, there's been no response. <br>
