Not processing your withdrawals! Lots money!

Made a withdrawal at 6pm on Friday using the express option and paying the additional fee. Luno has a processing time on the Saturday, but they did not process my withdrawal. What is the use of paying an extra fee if there is no benefits. I have no trust in Luno anymore. Who knows when I will receive my withdrawal if they have already missed a processing time slot. There is also NO way of contacting them. No email or phone number. Can bot even log a query on their website. Ridiculous! I'm done with Luno.
