banned for cheat ?? lol ??

I was banned for cheating!
but I have never cheated, I want to see proof of what you say, besides that day I have not even played .........
I spent over 500 euro in this game so I request a minimum of esteem!!
I ask that you give me an explanation.
I did not cheat!
think I put a lot of money in that account then why cheat?
but it's really not fair!!
I play for two years, I had never been banned, I always played legally, nor cheat, nor farm!
why I do this? to lose my ribbons I love so much!
to lose my account where I put so much money?
is abuse ...
