I tried earlier to buy some knight cash from the PUS. My transactions were declined because it said there was a mismatch with my billing address. So I tried different variations of my address, trying to figure out what might work. Well using the credit card didn't work, so I tried click and buy. Well click and buy declined my transaction 3 times. 10 minutes later I get a phone call from the fraud department at my bank, they asked me if I had attempted to make 5 purchases at knightonline.com and 3 purchases at click and buy. So apparently I am going to get charged $80 for nothing. Now gotta wait till Monday to call the bank and tell them to decline those charges. K2'D FTW ! ! !
