Blocked Radio/CD Player

Hi there, I have a Ford Bantam 2011 1.3 XL Bakkie. Had it since new and well looked after. Recently I foolishly entered the code to my Radio/ CD Player incorrectly three times as the battery went flat and had to be resetted. Now it stays blocked. The Ford Dealerships are not helpful at all and say there is nothing that they can do. I need to have it unblocked please. What now....
