BEST Manchester in Townsville QLD

Returned a electric jug to service desk, initial price $39, faulty casing released steam onto wife's hand, causing a slight burn. Received store credit for $19. I argued for the initial price, they said it had been marked down, so could not pay me the former price. That's our policy if you don't have a receipt. And proof of purchase, USAID rather heatedly that the proof of purchase was in front of them. Called manager, she backed her staff and said I was rude for wanting a fair go, seeing this item injured my wife. After a great argument she gave me a new jug, no exchange docket, no proof of purchase, so I had to walk out past security with a new appliance, didn't even check, could have took anything. Now , IF this one breaks down, how do I exchange it without a docket. Manager said , " come and see me, may have another argument". IS This K MART. Policy. Rude and abusive to elderly (76) customers. PATHETIC.
