No Satisfaction unhappy customer

I recently purchase an "Intelligent Health Bracelet" from this company who advertise daily via e-mail. After a period of about three weeks this device expired, and was no longer working. Sites states that there is a warranty. I made contact with this company on their web site where you complete a form with the problem and contact number at the beginning of October, since then I have sent an additional 5 mails to One Deal A Day <***> which is a published mail address with no reply. Their web-sites states that there will be contact within 48 hrs. I would not recommend this company
