When I tried to purchuse London gatwick 2004, it told me that the security check on my credit card had failed and told me to check my credit card details again and to try again later. How can I fix this problem. This problem occured when the three stages of purchusing came up - 'Establishing secure connection', 'Processing' and 'Order Approved'.
Call the credit card company, they may have something in a different order than you are filling it out.
What do you mean?
Just call them and explain the problem, they've seen them all before so they will know what you mean.
It always happens on my dad's credit card. Some of the time, the information you need to enter is slightly wrong and the card refuses it, so check that first. Then try as RM suggested 😉
Hope it works for you 😀
