Uh Oh! Sorry for the inconvenience. This is a rare problem, but the most common cause is incorrect information (even a mis-typed zip code) on the join form. So please enter each line item very carefully, and make certain that all your entries exactly match the information on file with your bank or credit/debit card company. If you experience further difficulties, contact Rick, the founder of Sexcams Unlimited, and he will personally see that your problem is solved.
