Clicks Fourways crossing refusing to assist with product

I bought a hair dryer from clicks fourways crossing last year August or September. I have used the same brand for 7 years prior and excited to get it on discount last year. The dryer blew while using it and caused a black out. I went two weeks ago to ask for a reprint on my receipt for Clicks to send the dryer to the supplier to fix or replace the unit. The employee at the till was happy to do so but the manager Rami refused to assist me saying they can't fix products on a reprint receipt yet the reprint and original proves where and when the dryer was bought. I worked for the brand years ago and I was in customer service I know as long as you can provide the box and warranty the dryer can be booked in for repair if it's under warranty and within the year of purchase.
