Feel like I have been Ripped off

Been asked for weeks to buy 2hr free play with 9 gold bars, since I was 1 short only having 8 I decided to buy 60 giving me 68. The minute I bought them the 2hr free play stopped but now I can buy 6hrs with 69 bars!! That means I am 1 short again. I only bought the 60 for the 2 hr free play and will not be purchasing more. I feel you have ripped me off and would like it refunded if you are not offering me it. Funny how 2 minutes before I purchased it I was still being offered the 2hrs
