Subco Inc. I have been trying to cancel a subscription for magazine Fresno, California

Months ago my credit card company calls me and says I am offered a free trial of magazines US weekly and Women's Day. I said I really wasn't interested. US weekly then starts sending me magazines. I tried repeatedly to cancel this magazine for months now and nothing has been taken I have tried numerous times and got no where fast. Either I lose the connection on the telephone or I get called repeatedly to ask if I have received my magazines in a timely fashion or if they were ripped. I have repeatedly told the company I want to cancel. Just like the person who was sent the Maxim magazines I have been told the same exact thing. I contacted Women's Day and they told me that they can't do anything it was Subco who did this and to contact them so they can cancel.  I don't get how these companies could get away with it. If I had a subscription for two or three years the company wants 1,500 dollars for the magazine. 49.95 a month are you kidding me. For once I want them to leave me alone and stop sending me magazines I don't want and don't read and can't even afford. I've gotten the runaround from this company and just want to stop being billed. I thought this was all taken care of when I received one of the magazines that said this is your last issue unless you want to renew. I never said I wanted to renew and never contacted anyone to renew. I had then stopped getting the Us weekly for a number of weeks so I thought everything was handled and out of nowhere I started getting them again. Then a few weeks later I started also receiving Woman's Day. This is so frustrating and I want this to be resolved.
