Brylane Home false advertising, item returned, promised full refund, no shiping charge and now they're trying to charge me Internet

I ordered king-sized bedspread advertised as coming with shams...no shams arrived with bedspread!  I called and was told they would be shipped separately..still no shams after several weeks...called again...was told the advertisement was a misprint and it did not come with shams.  Said I could buy them...I opted to return the bedspread and sent them a letter/cut up credit card, and said this was not the first time they had lied about their products/discounts and I no longer wanted to do business with them.  One of their reps called and asked me to reconsider...after telling her the story and how unsatisfied I was she told me there would be no charge for the return!  Lied again...now they're sending me bills (last one was $118) and adding late charges, etc. on every bill because they now say I owe shipping of $6.50!  I have an e-mail from them saying they received the return, giving me credit for only a portion of the purchase and adding shipping charges...this was received before the representative called me.  I sent a letter to their CEO in NewYork on February 3...still haven't received a reply.  There should be a class action against Brylane Home for bad business practices and FRAUD!
