Emirates - will think twice to use in future

Made a payment for over R16000 for upgrades for 3 people using their online payment gateway, OZOW. Payment was deducted off my account but when payment portal returned to Emirates, showed payment failed (which is definitely not the case !!!). A lady from Emirates contacted me, said I should put through the payment again as it "failed" (yet, still deducted off my account) otherwise can lose the upgrades that I need to get for my clients ! Told her if she is sure that it will not create the same issue as can't afford for it to go through twice with them saying again it "failed" . She assured me it will go through. Long story short, payment deducted AGAIN but Emirates again claiming have not received the payment ! So for a 16K transaction, I have now paid over 32K, still not upgrades, still saying payments not received and had the ***** to ask me to put it through a 3rd time!!!! Are you kidding me !!! I have send them proof of payments, gave them FNB's online payment verification links and insisted that their finance department find my payments, allocate to my upgrades for my clients and refund me my 2nd payment immediately as I have Forex payments that needs to go off. Who are going to explain to my clients if the upgrades are no longer available or suddenly more expensive as when I paid??? The woman I spoke to should not be in customer service as 1st thing she should have asked was for pop's and go to finance department to trace payments, instead she got rude when I got frustrated with whole situation !
