SHOCKING CUSTOMER SERVICE BA!!!

I flew BA 6200 dbn to jhb on Thurs 12th july and left my wallet in the seat in front of me. i was in the last row 'F' . i think 27F. i phoned BA jhb international as 45 mins later. They asked the cleaners and it was not found. I fortunately cancelled my credit card and 20 mins later an attempt was made to purchase on my credit card. Obviously BA staff or cleaners found it and DID NOT hand it in, but chose to ***** it and use my credit card. I have emailed kulula AND BA customer service TWICE, and Im STILL WAITING TO HEAR FROM THEM. SHOCKING AND THIEVING EXPERIENCE FOR ME!!!!! BA you have FAILED your customer!!!!!
