I had the same thing happen to me. Thought I just paid for shipping and handling on "free trial" of Acai Berry and instead got put on a "automatic shipping" order system and ended up being charged over $160. When I called the company they told me I agreed to the terms on their website which I didn't even see when I ordered the "free sample."
I think the Better Business Bureau needs to be contacted.
I had the exact same problem as you. I think a class action suit should be filed against this company. I never saw anything about calling to cancel. I just wrote refused didn't order on the package they sent but apparently they say they have no way of knowing that it got back to them.
I saw your post about this being an acai berry number. Now I understand why I am getting annoying hang-up phone calls from this number from 7:30a.m. and into the day. I made the mistake of ordering this "free" product only it was not free. They took money out of my checking account--unauthorized. You can report this to the District Attorney in Florida or whatever state sends your Acai berry(I did and I guess this is why I am now getting these calls) if they have done the same to you.
I've had 3 missed calls from this number since 8:30 this morning. It is now 11:00am. I don't answer calls from people I don't know or numbers I don't recognize. Of course, no messages were left. I did discover however, the last time this happened to me, the best way to stop the calling is to have someone of the opposite gender to yourself answer and say they have the wrong number.
