Play2Win Casino refusing to self-exclude

I have been trying to deal with a gambling problem for some time. I slipped off the wagon and opened an account on with play2win casino after reciving some marketing from them.

Between 18/03/14 and 22/03/14 I lost £300 at the play2win casino. I then came to my senses and emailed play2win support on the 22/03/14 informing them I was a problem gambler and asking them to close my account. I also provided them with other user names I had with their play2win site that I had previously had to ask them to close due to my gambling addiction.

I never had a reply from play2win support, but I did continue to get promotional emails. I know they must have reviced my email as a previous, unrelated, email sent from the same address had been answered by them.

On the 01/04/14 I clicked on a link from another promotional email from play2win, I discovered my account had not been closed. I got into chasing the losses I had sustained and one hour later had lost a further £400.

I emailed again on the 01/04/14 requesting that my account be closed and complaining that my account should have been closed on the 22/03/14 when I first informed them I had a gambling problem.

I have checked the play2win account in question and it remains open, in addition there was a bonus waiting for me.

Today I recived an email from play2win asking me to verify my account with security docs and sign a form to say that each listed previous deposit with authorized by me. My account remains open

I would like some advice as I would like the casino to do the following 1) Close my account and permanently exclude me 2) Stop sending promotion emails 3) Refund the deposits I made on the 22/03/14 of £400 as this was nearly two weeks after I contacted them to close my account as I had a gambling problem.

Any help would be greatly appreciated. I will try and attach the email I sent to play2win on the 22/03/14 requesting account closure.
