Coin Master complaint: BLATENT RIP OFF

I have been playing Coinmaster for about a year,as you move up the levels it get increasingly more difficult to attain the amount of spins you need and you are pretty much forced to make a purchase or your village can be destroyed which means you either have to earn spins or buy more spins. Recently I was 2 hammers away from obtaining 11000 spins on a couple of occasions I obtained enough hammers to get the 11000 spins but they did not add to the total. I ran out of spins and spent £25 buying more spins as I did not want to lose them as the reward session was almost finished.
Again I obtained enough hammers but again this was not added. I did manage to obtain a screen shot of the 11000 spin prize showing it was still available and also that I was obtaining enough hammers.
Several times I wrote to Coinmaster and they kept on saying that the game had finished when it had not and they made no mention of my photographic evidence. I asked them who their controlling body is ie a gambling comission and on 4 seperate occassions they ignored me.
I did not spend £25 for the fun of it I either want my 11000 spins that I EARNED or my money back
