publishers billing center scamed me out $275. for a subscription to Archaeology magazine. I have asked them for a refund of the subscription since 7/11 called and called and wrote to them I sent them copies of all the renew white city, Oregon

since 7/12 i have called and called to ask for a cancellation of the magazine  archaelogy magazine with no response from the company nor publishers billing in white city or.  They keep sending me renewal notices and ignoring the fact that they owe us at least $240.00 for the subscription that we cancelled back in august.  we obviously have overpaid and expect a check.  my last letter to them was 1/7/13 in which i threatened to report them to the bbb and the attorney general of nj.  I also spoke to the subscription dept at archaelogy and asked for a cancellation and yet the mag keeps coming
