I have tried to negotiate with this company about the $148 they have of my money. I used and kept one bottle of there pills and sent 4 back. I could not take them they made me very ill i ended up in the hospital dehydrated and informed them of that. I had told them a month before that they were not working and agreeing with me , She told me that they did not promise them to work in a month to continue taking them and that is when I became very ill with uncontrollable dirreahea and throwing up. gloria,Austin,Texas
