I purchased a sample of phenterthin in October, 2007 on-line. No where on the information provided on line did it make mention of having to purchase additional orders or that I needed to notify the company to cancel any additional orders. Sometime in November I received an email from the company stating that my new order was on the way. I immediately emailed back to cancel any orders and stated that no additional orders were made. I did find a telephone number in this email and attempted to contact the company at least 3 times. Each time a recording came on stating that the phone number was no longer in service. I did receive a package from the company which I immediately sent back with "cancelled" across the top of the package. I heard nothing from the company. In December, 2007 I received a charge on my credit card for $149.95, which I contested. After 2 months of "investigating", I received a letter from my credit card company stating that "the merchand did not agree to accept my cancellation request." I did everything that I could to contact the company, cancel any further orders, etc. to no avail. I will not pay this charge. I believe that this company is running a scam on the public.
