$1,500 Winnings not being paid

Ever since Mar. 14th when I first made a request to make a withdrawal on my winnings, I have been getting the run around. First off, I submitted all required documentation they requested to verify who I was. I had made the initial deposit of $30 from my Mastercard but yet they advised me that when they went to pay me my winnings , Mastercard would not allow the transaction of them crediting my account? Strange. Nonetheless, I choose a different form of payment of my winnings . The only other option was them issuing me a cheque. That request went in on March 18th. Then on March 22nd, I received an email saying that my winnings were not being paid out via cheque and instead were being returned to my account. They said that they had explained the reason in an earlier email they had sent to me (which i never received). The below is some of the correspondence I have had with this company. I would like to add that ever since I have joined with them, their form of communication is extremely poor. I have had to contact them on various issues - ranging from not being given the 100% welcome match bonus at the beginning, to asking general question on identifcation requirements, etc. Their response time - if they even respond which they usually don't - is very very delayed. All i want is to be issued a cheque for $1,500 on the winnings I won while playing on their site. I have sent them all the required documentation. My guess is that they delay the return, return the winnings into the account in hopes that the person just gives up and gambles their winnings all away back into their greedy little hands.
Further to my below email, i have to express my frustration that I have experienced ever since joining this online gambling site. I only joined because of a good welcome bonus offer as well as some decent reviews i read on Ask Gamblers. My experience has become a complete sense of frustration. Is there a phone number I can call in order to actually talk to someone? Days go by before i ever get a response - sometimes I do not even get a response. This is totally unacceptable. Now it appears that my request for my winnings to be sent to be is being denied. I have submitted absolutely EVERYTHING that was required in order to be paid my winnings. I want this dealt with other than emails - especially when i do not get any replies.

I have submitted my current B.C. driver's license, a copy of my recent utility bill, a copy of my original $30 Mastercard deposit made to Jackpot Paradise.
Kindly, pay me my $1500 winnings as per my request from two weeks ago before i put in a formal complaint.
