Ramit, Sean never said that you attempted a fraudulent charge with him. As another business owner with an online website, small glitches can happen for unexplained reasons it seems.
You said that you called to cancel the payment the same day, so it doesnt sound like you gave Sean much time to make this right. Credit card companies are cracking down to prevent fraudulent orders, so if you list an incorrect billing address, or even just the formatting of the address doesnt match what the bank has on file, it can and will decline a payment...something as simple as writing out the word Street instead of abbreviating it at St. ca cause a payment to declined because of a bad address. It happens to us as well. When this happens, it will show as a pending charge on the customers account, but we as the merchant are not physically allowed to accept the payment once it has been declined. We do not even get a notification that the payment was unsuccessful, so Sean would not have known that you tried to order had you not contacted him.
Because there was an issue with the credit card, Sean tried to offer an alternative payment type using paypal, in which you just said that you refused to do so.
Also, Sean is not "on the staff" at the Z forum. He is simply a paying vendor over there just as he is here. The administrators on every forum has final say on what goes on, so no vendor has the right or the ability to ban a member for any reason. The only control the paying supporting vendors have over the forum is being able to moderate their individual vendor forums. Even then, all that can be done is that we can edit or remove individual posts, not ban members.
Sounds like you lost your temper over what seems like a very easy situation to manage, then got all bent out of shape because you assumed Sean is the one who banned you from the Z forum when he had no control over it. Now you are jumping from forum to forum trying to bad mouth his name when the man never took a cent from you, and only tried to help you resolve an issue with an order that was not showing up on his end through the website.
