Walt Disney Movie Club refused to refund my money after sending monthly selection card with check. They sent wrong movies twice won't give money back but now will issue acredit credit Neenah, Wisconsin

I ordered three movies off the monthly selection card and sent $45 to pay for it. They sent back one wrong movie. I sent the whole package back with a nastyletter and asked for a refund. They kept my check re fuse to give it back. They sent two other movies I did not order I sent those back. I made a huge compliant stated I wanted my money back and postage for both shipments. They also will not let me out of the contract unless i pay them $75. They finally sent me an email stating they would give me a $55 credit. I ordered a movie from the monthly card, got it and they credited it from that amount so have $25 left . I have two more movies to purchase to get out of the contract. can't wait. I can buy the same movies at Walmart or amazon . com for a better price!
