I don't know why I am even wasting my time responding, but here goes....
1. WGT provides unlimited free balls to all registered members.
2. When you purchase any upgraded balls it lists a durability factor. The durability factor is explained in the FAQ's. Here's the link : http://www.wgt.com/help.aspx#equipclubs
That being said, you either failed to read or failed to comprehend the details of what you were purchasing. Either way that is your problem, not WGT's.
3. "PRODUCERS OF GOLF BALLS ARE BEING ASK HOW LONG A GOLF CAN BE USED IN A ROUND OF GOLF AND THE LIKELY HOOD OF IT NOT LASTING THROUGH 3 ROUNDS OF PLAY."
When was the last time you saw a pro use the same ball for a whole tournament? Doesn't happen. As for amateurs I think you would be hard pressed to find any that use the same ball for 3 rounds as well. Amateurs are either not good enough to keep a ball for 3 rounds without losing it or the ones that are good enough to go 3 rounds without losing one are probably fairly serious golfers and would switch them out anyways.
Read the article http://www.golfdigest.com/golf-equipment/hot-list/hotlist_howlong Baed on the info in the article 100 hits at 125 mph and the balls is trash. So as far as I can tell, WGT is giving you a deal because the balls last far more than 100 hits.
On a side note, the new product line for the fan store should be tinfoil hats with the WGT logo. It'd probably be a number 1 seller.
