Complaint Review: FLY FREE TRAVEL & Dialing USA Inc

This company called my cell phone and told me that for $3.95 they would send me on a $1000.00 shopping spree for looking at thier product and all they needed was my checking account No. to pay for shipping ($3.95).I gave it to the caller. Then The caller proceded to mention other offers which I refused. I told The caller That I changed my mind to the first offer, the caller said OK and hung up. The company Fly Free Travel removed $129.00 from my checking account and Dailing USA, Inc removed $79.94. I since closed my checking account. I called the company & wrote letters. they said i had agreed to the offers & that they have recorded proof. I challenged thier proof & they agreed to give me a refund, but I have to sign a refund agreement. Which I received today. I still don't trust this company. I don't think I should sign. Any Advice?.
