Unsatisfied with Makro Grey stock

We purchased a Laptop from Makro the price of the Laptop was R16000.00 The Laptop was defected and Makro refuses to refund our money the want us to wait 21 days for the Laptop to go to Gauteng and come back if my daughter doesn't have a Laptop within the next few days she has to wait a whole turn to start her course this is putting a damper in her career I Respectfully requested a full refund but Makro Springfield park refuses to honor they refund policy which says if a customer is unsatisfied with the product purchased they are entitled to a full refund if the product is defected according to Makro return policy I am not going to be inconvinced by a company that sells defected products
