Garcinia Cambogia review: natural garcinia cambogia and natural green bean coffee cleanse

I ordered a sample of the Garcinia Cambogia, they sent me a bottle of that and a bottle of the Green Bean Cleanse, which I did not order. I thought I was paying $4.99 for the one sample. I was waiting for the charge on my credit card. When it finally came they had charged me $89.99 for the Garcinia and $89.95 for the Green Bean Cleanse. I am disputing this with the credit card. Now they have sent me another bottle of the Green Bean Cleanse and I have been trying to reach them to get a RMA number so I can send it back. On the Dispatch Note I received with the bottle, it says it will not accept the package unless it has that number on it. I have been calling them every day since I received the product. I have 14 days to return it, but I don't know what to do if I can't get the stupid RMA number, whatever that is. Help!
