Defy 13ltr washing machine

We visited Game Retail park in East London to report our Defy 13ltr washing machine being faulty. I unforetunately misplaced the purchase slip, however I showed the bank statement of purchase proof. We were told this will be referred to Jhb for the original slip to be traced. It's been over 5 weeks and no one has contacted us. The machine is still faulty with an error code E6. Please I urgently need some feedback on this matter
