Circulation - Tens Device.

My mother bought a Circulation Tens Device a year ago from a temporary stand at a mall in Johannesburg for R3000. The salesman assured her the warranty was for 5 years through the main company in Cape Town, the paperwork with address was included in the devide. A year later the machine is not working. Kiera Ward Maclou answered my e-mail (there is no phone number working) and tried to sell me a new device for R1200, stating that as it was bought at a temporary stand the warranty is not through them. I would strongly urge anyone not to buy their device.
