New drill-driver faulty

Purchased Ryobi drill-driver on 4 Nov 2015 for R1999,00. Only used tool on 14 Nov 2015 and it stopped working. Took back to Makro on 15 Nov 2015. Was informed that item must go back to Supplier for evaluation. I requested replacement if unit was faulty, express notice not to repair as unit is still new. I was informed that battery was faulty and supplier will replace. My request is a refund if item was faulty. Makro will not replace with hew unit or refund. It is 3 weeks and response to my request. My repair number is ***. My email address is ***<br>
