Okay. I had 133k and tried to rankup to C-Prisoner. it did not work, but it still took my money. so, i did it again.. same thing happened. lola even gave me money to test it out and, again, it took my money and i didn't rankup. :/
I think this is suppose to be in the Help section. Anyways, do you have any evidence of you purchasing C?
Can you enter C block? Are you a donor? Maybe your donor prefix is there instead of your C prefix, however you are registered as C prisoner anyway?
