I've spent money and can no longer get free kstar offers

I apologize if this is not where I should be posting this, but I'm getting fed up with trying to contact them on the app and receiving no help. Immediately after spending money on the game a few months ago (buying kstars and renewing my vip subscription after the free trial ended), I have been unable to get any free kstars by watching videos or completing any offers (such as tapjoy). At the time I figured it was just a sly way to get more money out of you for a week or so and then maybe the offers would come back. At this point it's been over 3 months.

I contacted glu support many times. I told them my problem over and over, growing more frustrated each time. Every time they gave me a copy/pasted response that essentially said 'we don't always have enough videos, sorry!'. I kept explaining that I knew that wasn't what was happening, the button to click for 'free kstars' was gone and by that point I felt like I was being completely scammed. I read where others had the exact same issue. They spent real money on the game, only to be unable to complete any of the watching videos/other free offers ways of getting free kstars.

I spent around $50 on the game and while that may not be a lot to some people, it is to me. Especially when it seems like it came with punishment for further play. I have been tempted several times to spend more, but I refuse when I'm being ripped off. I wasn't even offered anything for pointing out these issues...I guess that's because they're on purpose to make more money while penalizing paying players.

I have been seriously considering quitting playing and even contacting itunes to submit to get my money back. I really don't want to do that because I enjoy this game, but I've been offered no help and it seems like this is a reoccurring consequence of actually spending money on the game. I just want this fixed.
