midwest center Charged me TWICE for vitamins I cancelled Internet

I ordered TRIAL vitamins from MIDWEST CENTER for STRESS and ANXIETY, they asked for my credit card info for the shipping and dummy me gave it to them. After giving them my credit card info I told them I DO NOT want to be charged for any future vitamins. I wanted to try them out first. They of course said there would be no charges and dummy me believed them. well.. a month later I got my first 68 dollar charge from MIDWEST CENTER. I called them up and asked for my money back, that I didn't even open the box up that they came in, they said we don't refund stuff like that cause it's a food product. hmm.... they never should have been sent out in the first place! Cause MIDWEST CENTER said they wouldn't charge me. So I did a cancellation just to be safe that I wouldn't get charged again. A month goes by and I get a second CHARGE... I called them up AGAIN!! told them I DO NOT WANT ANYMORE CHARGES ON MY CREDIT CARD and I WANT MY MONEY BACK!! same results as above. So I threatened them with my bank and told them I wil be filing a civil suit and I WILL GET MY MONEY BACK! she replied, go head! we deal with civil suits all them time! hmm... really... And thats exactly why MIDWEST CENTER FOR STRESS AND ANXIETY belongs right here!
