I joined playhippo about 3 months ago. After playing for a while I decided to take a cooling off period for 4 weeks. I then received an e-mail from them advising that my cooling off period was over and that I was able to play again and all features of my account were now enabled. I logged back in and deposited a couple of times then I won £1700. I withdrew this amount from my account however 2 days later I received an e-mail from everymatrix telling me that I am self excluded from one of their sister site and that my winnings and deposits are void. I have tried to contact them explaining that they allowed me to open an account and emailed me after my cooling off period to say I can play again but they won't reply.
