LeoVegas Casino - Account locked for unknown ''security reasons''

I set up an account with Leo Vegas after it was recommended to me by a friend. Before I made a deposit I sent off my passport and a copy of my bank statement to verify my details in order to prevent any withdrawal delays in the event that I should be lucky enough to win. Anyway, the verification process was completed fairly quickly and I received the following e-mail:

Dear customer,

Thank you for sending us the information that we requested from you.

I have now approved your documents, and verified your account. I have also added 10 free spins on the game Starburst for you to enjoy!

If there is anything else that I can help you with, please do not hesitate to contact us again.

So, now that my account was fully verified I made my initial deposit of £120 and chose not to opt in to any bonuses. The £120 didn't last long so I made a second deposit of £120. This time I won and over the course of a few days my balance fluctuated and I eventually made a withdrawal for £3004.

The day after I made the withdrawal I attempted to log into my account to check wether the withdrawal had been released or wether it was still pending but I was greeted with a message informing me that my account had been locked for security reasons. Upon contacting customer services via e-mail they were unable to give me any details as to why until they had a relevant update from the team.

After reading other peoples reviews regarding this casino I have a feeling they are going to drag this out and do whatever they possibly can to avoid paying out which will result in me having to pay Solicitor fees in order to get my cash. Meaning the end result will be considerably less than £3004 once I have paid for the assistance of my solicitor.
