Withhold my withdrawal

I recently opened an account with CasinoKings and did the sign up offer they had going which i came out with some winnings, once a withdrawal was asked i was asked for ID which i fully expected, i sent that ID on the 28th of April. On the 29th i received an email stating i had to re send ID that had been notorized. On the 1st of May i went to the lawyer and got all the ID they required notorized just like they had asked and sent it in the same day. 3 days later i had not heard anything back to went on Live Chat and got told the security team was reviewing it and i would receive an email. 7 days later i went back on Live Chat as still nothing from them and got told the exact same thing, except this time i got told we will make it a priority so you get a faster respone. We are now 10 days later and having just been back on live chat to be told "the security team are reviewing your ID and you will receive an email in due time" im getting a little bit annoyed. I sent in the ID they wanted in the first place, i then drove for 45 minutes to a lawyer and paid the lawyers fee for getting the ID notorized and yet all i am doing is getting fobbed off.

I signed up to Casino Kings after going on their site on my mobile and reading through their terms and conditions (of which i will attach the screenshots of these, as i always screenshot these for the exact reason this is now happening). I took part in their welcome offer of a 100% bonus up to 200 GBP. Their t&c's said no bets over 5% of the bonus received, so i went ahead and stuck with my normal 5GBP and lower spins. Whilst wagering, i went on live chat a few times to ask them if my wagering was complete, they told me each time how much i needed to do now after checking my last bets, not at any point did they tell me that the 5GBP spins i was doing were not allowed, which makes me believe that they changed their t&c's after i had completed the wagering on purpose. I completed wagering and finished on an amount of 2609GBP. I then had an email, actually congratulating me on my winnings. I then made a withdrawal request, and it took them over 4 to 5 days before i even had a response, i then got an email saying my account was closed and my deposit had been returned to me as i had breached their terms and conditions of the bonus. I then emailed them back, saying that i had screenshots etc, and didn't get a reply for at least 2-3 days, finally i got a response, with no answers to my questions a points, but just telling me exactly the same as what they already had in their previous email, they gave me an email address and said i need to email that address to raise a complaint, and it HAS to be done within 7 days of when my account had been closed. I emailed this address immediately, and it has now been well over a week and still i am yet to receive any form of response from them, hence me now raising this dispute with yourselves.
