telebrands,inc. when ordering online your credit card information is accessed twice. and they don't want to give you your money back. Internet

i ordered online from this company telebrands they were advertising for slimaway belts and for purcharsing one for ten dollars you could get the second free if you included extra shipping and handling then you would be charged twenty dollars but they double charge your card for a third belt and you then would owe thirty dollars plus tax and shipping and handling,  i ordered them on 10/24/11 and i got them in four days i then called them before they shipped to let them know that i only wanted the one plus the free for twenty bucks and that they needed to straighten out my card because i was double charged and from then i have been getting the run a round i sent all three belts back and then called them and told them when to expect them and they kept saying that once they get it that they would reverse it back onto my credit card within 5-7 days? so yeah right they got them back in three days and on 11/14/11 i sent them back and i kept calling to see when my refund would be back on my card, well i was told that on 11/21/11 it was being processed and within 5-7 days after that date i should have my refund of 30.98 so today is 12/04/11 and i have yet to see my money back into my checking account?   this company is very sneaky and deceptive when it comes to the consumers money?
