Fix my problem now

So tell me why I brought the thing where you can use the metallic colors on my phone ( I was using my gmail to make an account) then when I logged into recolor on my tablet I have to pay for the metallics again? Can you cancel my membership and stop making me pay. Because now this app annoys me because I can only use the metallics on my phone. Cancel my membership and stop making me pay.
