Lost payment Terrible Customer experience

I am terribly disappointed with your service, I have made a payment using your SID portal the funds were taken out of my account but you claim to not receive it. I have spent over an hour to your call centre and both representatives have dropped the call on me. Then I post to your Facebook account requesting some assistance and you promised to call me back but no call back. I speak to guest services on the airport and your answer to the dropped calls are it's technology. I have confirmed with my bank that payment cleared and received a proof of payment. This entire process has been a joke. Nobody is willing to take ownership for the poor experience that I have had. I am seeking a full refund and compensation of my time spent having to chase you up. I have flown almost every second week with your company but after this. I will take my business elsewhere and ensure all of social media is aware of this.
