Titus purchased an electric coffee maker from Technosales Pty Ltd for $3,000 for his personal use. After two weeks, the coffee maker started to malfunction, even though Titus had been using it in accordance with the manufacturer's instructions. He phoned Technosales, who told him to return it to them. When he unplugged the electricity from the back of the coffee maker, he received a severe burn on his hand from an electric shock from the power cable.

When Titus returned the coffee maker to Technosales, they said that they would return the coffee maker to the manufacturer for repair. Titus, however, demanded a refund, which they refused. They referred him to the term, printed on the sales receipt, which said "No refunds shall be given for returned items".
