Poorest service at Makro refunds and returns!

Good day. I am utterly dissapointed about the service I received at Makro Silverlakes. I bought a Phillps steam iron on 10 December 2019 at the branch. The iron had a 2 year Guarantee. One month later the iron switched offwhile I was ironing and would neither start nor heat up again. I took the Iron to refunds on 12 Jan 2020 at the same branch, just to be told that the iron need to be send to an assesment center and that it would take 2 weeks. What I need to use in the mean time to iron was a big question and I still didn't get an answer for that. Not something that I would expect from product with a 2 year guarantee though. 5 February 2020 exactly 3 weeks and 2 days later I received a sms that my iron was ready for collection. Sad to say that when I received it today, according to the assessment report there was NOTHING wrong with it. Something that I don't understand at all as the lady assisting me at refunds on day 1, plugged the iron in and neither the light was burning nor did it heat up. The worse part, besides recieving my "broken" iron back was that while I was standing at refunds waiting to be served, 2 persons received a refund for faulty purchases. When this was questioned the answer was that the iron had been used. For Pete's sake, how do you find the iron to be faulty if you don't use it. This was my last puchase at Makro! Poorest service I have ever received ar refunds and returns. Funny that competitors would immediately replace the iron....
