Cellma transaction error
Recently finished the assessment for an initial class 1 medical application on Cellma before i aim to begin my training as an airline pilot.
Upon completion i'm prompted to pay a £16 fee, which, sure, i can do. However no matter how many times i try or how many different cards i use the transaction isn't able to go through and i'm met with the same message, 'your last transaction was error, please try again'
Is there any way around this?
Thanks
