I used to play, soon realised they wanted your money to buy clubs, balls etc., so sat through a good few videos, filled in questionnaires, signed up to 1 month trials etc to get some free cash. After doing all this, very little of the promised credit came through and when I sent an email asking why, they said "It's down to the 3rd party company to tell us you did what was needed, tough doo-doo if they don't, take it up with them".
Unfortunately, questionnaires-for-stupid-banks-and-other-companies-wanting-useless-feedback.com don't have a WGT Credit department, so needless to say I haven't really played since.
The putting is also a joke, I came very close to throwing my iPad out the window on more than one occasion!
