Rude, Hung up on me, won't listen Mesa Arizona

 I ordered Pure Green Garcina over the phone and was told to try it for 14 days and if I didn't like it I could cance within those 14 days.  That is what I did.  After receiving the product, I called to cancel within 7 days.  They shipped the product anyway and I refused it.  They charged it on my credit card and I disputed it.  I didn't expect to get anymore.  After 2 months I noticed there was another charge on my bill.  I haven't received the  product yet, but I went ahead and disputed that charge.  I called them and they said I had not cancelled and proceeded to cancel 7/1/14 and told me I had to pay for this charge also. I tried to talk to them but  they hung up on me 3 times.  They are very rude.
