Refund defective printer within 7 days of purchase

I will never advise anyone to purchase a HP printer from Game My printer wasn't printing right after just a few days if use. I returned it to the store within 7 days and demanded a refund or exchange. The manager informed me that the printer must be send in for assessment. From start I made it clear that i didn't want a refurbished printer. I paid for a new printer. It has been more than 3 weeks now and still no reply from game. The store staff and managers customer service is poor. I bough a printer because i need it daily for my work. Now one month later i still dont have a printer. I feel Game should've already given a refund as the item was defective and returned within 7 days of purchase. Why should i as the consumer take the loss? I need a refund asap game!
