It's pretty straight forward. The retailer has the right to choose which of the 3 rs (repair, replacement, refund) he gives to you. You equally have the same right to refuse what he is offering and insist on a different r. If you can't come to an agreement, you have to go to the Small Claims Court. There you have no real chance of winning, if the retailer's offer was reasonable. In your case, I can't really see the Small Claims Court agreeing with you. It's after all not the retailer's fault that you bought a new one from a different retailer.
