Skyflake:
it has taking balls from my invetory wit out me playing them,pretty simple thing im asking
Well I did a quick look - Since the 11th Feb you have bought 3 sleeves and played 13 x 9 hole RR and 6 x 18 hole RR and 16 x CTTH games = at least 950 "hits" (I did not count but took a rough average over those scores)
The ball gets about 120 hits before being worn out so the games played equates to roughly 8 balls used. Now I don't know how many were in your bag at the start or how many you have left, but to me appears to be normal wear and tear (and thats also the assumption you did not lose any).
I cannot imagine WGT is giving you their weekly special buy 3 balls and get 2 but you could email them with your concern and give them the reasons why you think you are being shorted. To my eye, it appears to be normal usage.
