Complaint Review: Bingomania.co.uk

I joined bingomania.com a while ago and when they started a UK version, I joined that also. The site bingomania.co.uk was for UK residents only and players from the USA site could not play here.
Last week I won a large amount on a slot game on the UK site. I got lucky or so I thought and hit 5 wilds. I tried to make a withdrawal of the 6000, shaking as I did so. To me this was a large amount of money. I was so excited.
I had an email to say my account had been closed and I would not get the money as I had multiple accounts. I replied that I only had the one. They replied back to me saying I had another id which was the one at the USA version of the site.
I tried to explain that the other id was not for their site but they are ignoring my emails now.
I am gutted as I had told my 3 grandchildren I would take them to Disneyland when I got the money through.
If I had broken the rules why was this not pointed out when i signed up.
Please can anyone help me.
