mrbit, As marioh said, send them an email - they might be willing to work with you.
You didn't say, but if you already had one yourself and now you have 2 of these I would think WGT would be at least willing to refund your credits - makes no sense that you would buy 2 of the same club. If this is your only one, you might be out of luck.
Good Luck...
Joel, Just a guess but I'm assuming they don't won't some of the better players, who have earned a boatload of credits, to be able to gift the better clubs for free to others - I'm guessing they want to be able to make money off all of us, which I have no problem with. If this is the problem, maybe they could require you to purchase credits when gifting pro & master clubs - just a thought.
