Of course you can get your money back, Unless as you say signed a contract which clearly stated that it is non refundable then they have to refund you To make claims that money is non returnable they have to provide documentation to say as such and have to prove they gave it to you. Putting on their website that monies are non refundable isn't enough, they have to physically provide the literature stating such conditions.
Write to the head office, pay them a visit personally and also get a smalls claims court action going if all else fails..
Personally I wouldn't stand for it and go to the office and see them face to face and don't leave until they give you your pennies back...
