R900 to repair a R1000 Air Fryer on guarantee

I bought an Air Fryer from Dion Wired approximately 18 months ago. It has been lacking power for the first 5 minutes of use and then reached full power. Went to Dion Wired Boksburg to ask them the guarantee period on the product, as i had thrown my box away already. I was told that it has a 2 year guarantee. A week later, on the 26/03/2015, i took the product in to send for repairs. I was contacted after 1 month on the 22/04/2015, to be told that it will cost me just onto R900 for the repair. When i then queried the guarantee, i was told that i only get a 2 year guarantee upon product registration. Firsty, incompetence from Dion Wired staff who assured me that the product has a 2 year guarantee. And secondly, a ridiculous R900 quote to repair an item that costed me R1000.<br> I wasted my time sending the product in. 1 month since it went in, and probably another month till i get it back still faulty.
