Fraudulent Company (Tryrevblast)

After reviewing "satisfied customers" i made one payment of R1055.00. Eventually received one supplement (which does not perform as stated) and noticed yesterday that 7 other payments of varying amounts have been debited to my account? (Total R6664.00) This is obviously a fraudulent site with a sinister ulterior motive. I am unable to make contact with the company involved, and must question how they are able to instigate fraudulent transactions in this manner?
