Product does not work and is a *******.

About 5 weeks ago, I purchased your FlashnGo from Silkn. Because it was a large investment for myself, I did a lot of research and believed the product would be good. I bought it from your section in The Game store at the Glen shopping centre. They told me they can only give me a 14 day money back guarantee. I bought it thinking it would work. After the 14 days, with no results, I decided not to return it, since all the info I got about the product told me it needs a few applications. Only being able to do a certain area once every 2 weeks, I obviously hadn't seen any results. I decided to keep it and push on. Today the cartridge finished. So, I did legs twice, beard twice and chest twice. Supposedly that is 5000 flashes as the device promises. So I thought I need to go get a new cartridge. The Homemark store has a cartridge for R399 that delivers 1000 flashes. So am I to assume that I would need a new cartridge every week, since the 5000 flashes lasted only a month. Therefore, I must pay R1600 every month to keep using the device, with no promise that it will work. I know my 14 days are up. I am just so angry that I have been cheated and
