No Right To Reject

It is important to note that, within the reasonable period after the sale the consumer does not lose their right to reject the goods/require their money back merely by agreeing to let the retailer try to repair them.

If the consumer returns the goods, as not conforming to contract, and asks for his money back within a reasonable time, he may decide/be persuaded, to let the retailer make an attempt at repair. After he had given the retailer a reasonable time to complete this, with no success, he could fall back on requiring a refund or replacement. This might be because the repair was not carried out promptly enough or because it was not repaired to an adequate standard.
