Poor luggage quality and poor customer service

Hi. I am frustrated and disappointed at Makro. I dont know what to do. I need to travel in January and do not have a suitcase. I bought a 3 set luggage last year for R4000 last year. The brand is Elegant and they are black and shiny. Few days before its annivesary, the big suitcase' wheels came off. They were dangling and are still dangling. Its not good quality at all. On further observation, I noticed that the handles are also weak and they will come off soon. I can also see that the other 2 smaller ones will suffer the same fate with their wheels since the quality is poor. I noticed this after the incident and when i was examining them. Overall, its poor quality sold at a higher price. I informed their customer service who sent me to the shop for a refund or exchange. On arrival at the Makro shop, I was sent back as it was a few days past the year (I didnt know this at the time as I didnt have the receipt and customer service had the card number to check this out. I also told customer service that i did not have the receipt). I was given an email to launch my complaint. I sent my complaint on the said email but there was no response or acknowledgment. I subsequently sent it to other email addresses, but it has been quiet. No one has bothered to respond months on. I am stuck with suitcases of poor quality and they are useless to say the least. It seems Makro buys poor quality and sell expensive to make money and do not want to take responsibility for it. I am a savvy traveller and have bought suitcases over the years, this is the first time suitcases are done within one year. Even market suitcases i bought over 10 years are still going strong. Makro are committing daylight *******.
