I would suggest opening a thread in the appropriate section on this forum (mining section?) & explaining your situation as much as possible with all the proof you have here - make a noise - it seems to be the only way of attracting any kind of response from cex as has been proven in the past on many occasions

Excellent idea!
If anyone else has a complaint they would like to share, please feel free to add a comment to my thread at:
