They claim NO HASSLE-NO QUESTIONS-NO TIME LIMIT GUARANTEE !! THEY don't respond to any contact attempt!!The blood pressure herbs were supposed to work in 87% of the cases-guess I am one of 13% that it does not work on!!I tried to contact PHARM EAST thru their website-no response!!I then called the telephone number on my invoice & left a message- nothing so far-been about a week!! The company appears legit as far as any thing I can find on internet,supposed worldwide unsolicited acceptance of there products makes it appear so!! If that is the case, they may not get many requests for refund!!
