I has extremely bad experience with the seller as Alibaba. If you care enough to look at my at the statement I provided yo you of how I thought that the seller was fraud. His activity of of removing the label of the chemical I bought was not acceptable. Hence I could not be certained of the product that I bought was not fake. Alibaba did not investigate my case as well The refund policy is a hoax. I have no face in your company as well since I have no contact back from you. As a result I refused to deal with Alibaba anymore in the future.
