Incompetence of team-Newly bought broken Defy Oven

My mom bought a four plate free standing defy stove in March 2015.. there have been issues with the stove<br> since day 1.. smoke came out of the oven.. reported the issue at the OK<br> store in bredasdorp. they sent technicians out to replace the thermostat,<br> then they came to replace the light and still there are issues with the<br> stove.. we want the stove replaced but the manager at the store said it's<br> not their problem and we cannot leave the stove on their premises after driving several kilometres to bring the newly bought stove to the branch...The manager advised that Defy has to come and collect the stove (the stove was bought by OK Furniture and not Defy) The onus should be on the branch to sort out the problem and not the client.. it's been 7 months of endless problems.. i would really appreciate response.. as too<br> what needs to be done going forward, My mother is a regular shopper at OK furniture and is very disappointed. <br>
