Call them and ask them about!

There might be a chance you wrote wrong account number / card number or there is some problem occure with bank. They sent you a letter and it lost in post or somewhere or throughaway in bin by your house mates which is usually happen with students.

So dont think you are going to get a free visa . There is a chance they will send your appliction back with non-payment argument.
