DISGUSTEING SERVICE & BILLING ERRORS

I am highly unimpressed with Swiss air and the billings team and customer service team.<br> <br> <br> <br> On September the 6th I had purchased my air tickets online for my December holiday for my partner and I , which was a total of ZAR 27 847,44 deducted from my debit card . While on holiday this weekend to my absolute shock on the 11th of September you went ahead and deducted TWICE a total ZAR 13923.72 X 2=27 847,44. I was on holiday with my family , celebrating my engagement , and yet I had to stress and worry for the mere fact I was deducted , and had NO MONEY left in ,my account to do the activities I had planned for my family and I.I am highly aggravated and I want this issue resolved immediately !! I will give you 2 working days MAXIMUM or I will cancel MY FLIGHTS AND GO BACK TO USING BRITISH AIRWAYS who has never giving me such bad experience and service.<br> <br> I have tried calling asking for help , no one has answers for me , and everyone does not seem to know how to handle this situation!!!
