Closed my account and withholding winnings with no explanation or reason

I opened an account on 4th October 2016 and made several deposits. I had been playing for a couple of hours and was beginning to have some luck and had a balance of approx £80. I suddenly received an error message and asked to reload the page. Upon doing so, I attempted to log in again but was denied with a message stating my account had been disabled. I have tried contacting customer support but have had no response. The live chat section appears to be unmanned by any personnel on their end. I have done as much research into the owner of the site and can find no evidence of any sister sites that I may have self excluded from. I have received no correspondence from them whatsoever.
