You do have the option to ask for a partial refund if you want to use the sheets.
"Who can the consumer claim a remedy from?
The supplier, if goods do not meet the consumer guarantees for:
• fitness for any disclosed purpose
• matching sample or demonstration model
• undisturbed possession
• undisclosed securities
• an express warranty given or made by the supplier.
The manufacturer or importer, if goods do not meet the consumer guarantees for:
• repairs and spare parts
• an express warranty given or made by the manufacturer.
Both the manufacturer or importer and the supplier, if goods do not meet the consumer guarantees for:
• acceptable quality
• matching description.
A supplier of goods cannot refuse to help a consumer by sending them to the manufacturer or importer.
Remedies for failures with goods
If goods fail to meet a consumer guarantee, the supplier who sold the consumer the product may be required to:
• repair or replace the product
• provide a refund
• provide compensation for any consequential loss.
When the problem with the goods is minor, the supplier can choose the remedy—either a repair, replacement or refund.
When there is a major failure, the consumer can choose to:
• reject the goods or services and either choose a refund or a replacement; or
• ask for compensation for any drop in value of the goods or services.
Where a good fails to meet the guarantees for acceptable quality, repairs and spare parts, matching description (stated by or on behalf of the manufacturer/importer) or an express warranty given by the manufacturer/importer, a consumer has the right to recover damages from the manufacturer/importer of the goods.
If the consumer purchased the goods from \the manufacturer/importer, their obligation to provide a refund is the same as any other supplier.
What is a major failure with goods?
A major failure with goods is when:
• a reasonable consumer would not have bought the goods if they had known about the problem. For example, no reasonable consumer would buy a washing machine if they knew the motor was going to burn out after three months
• the goods are significantly different from the description, sample or demonstration model shown to the consumer. For example, a consumer orders a red bicycle from a catalogue, but the bicycle delivered is green
• the goods are substantially unfit for their normal purpose and cannot easily be made fit, within a reasonable time. For example, a ski jacket is not waterproof because it is made from the wrong material
• the goods are substantially unfit for a purpose that the consumer told the supplier about, and cannot easily be made fit within a reasonable time. For example, a car is not powerful enough to tow the consumer’s boat because its engine is too small—despite the consumer telling the supplier they needed the car to tow a boat
• the goods are unsafe. For example, an electric blanket has faulty wiring."
