Worldwinner Unfairly banned me from site after I won money. Internet

I have been a member at worldwiner for about 5 years now. Recently, I have been very successful on this site and have won some money. At this time I had about 1000 USD in my account and 550 USD coming to my pay pal account. This monring I received this email from worldwinner...

I responded to them with this email...

I would like to fight your decision to remove me from your world winner site. I only have one account whick I have had for 5 years. I have dial up internet and have a lot of difficulty staying connected.
I have had some fortunate luck on yur site lately which has assisted me with my bills and some extra things for my home. When I lose my money on your website, there doesn't seem to be a problem. How come now that I am winning, you are taking away my winnings? I have not cheated, used any programs to improve my scores, or anything like that. I have just simply gotten good at playing your games. I have won this money fairly and I expect to at least receive what is in my money account on your website. I am so disappointed in the way you are handeling this, If you think I am cheating do an investigation and prove it. I have never cheated and I am uphauled at the accusation. Please reconsider my participation in your progam. Otherwise, I will make sure I tell all my firends and family how UNFAIR your gaming site is and if you win money you will no longer be
allowed to play there.

Please respond to this message as I am expecting a complete explanation. Thank You
