A business must not accept payment or other consideration for goods or services if, when it accepts it, it intends not to supply, intends to supply something materially different, or there are reasonable grounds (of which it is or ought to be aware) for believing it cannot supply within the period specified or, if none, a reasonable time. Having accepted payment (in whole or in part), it must supply all the goods or services within the specified period or a reasonable time, unless the failure is due to another person or a cause beyond its control despite reasonable precautions and due diligence, or the customer agrees to a replacement.
