Denied the sale price for booked flights

On the sale yesterday I had selected and had made sincere attempt to pay with my FNB credit card. If the system had notified me that the transaction was not successful I would have made further attempt(s) but there was NO info given. I checked for email or SMS but nothing indicated a lack of success. First thing this morning I checked for SMS or email but nothing. I then spent a few hours this morning to try via Kulula then FNB only to discover there was no transaction.<br> I have purchased the exact same bookings using the same card and same information entered. However the cost of the fares has increased from R2012.08 to R2258.68 through no fault of mine. Perhaps your system was overloaded. <br> I would really appreciate that under the described circumstances you would arrange to refund me the R246,60 increase I have been forced to pay through no fault of my own.<br> <br> Their reply was disappointing
