Makro online return service is poor

I bought a tv stand online at Makro which was delivered the 29th of January 2025. I was unable to assemble the tv stand because the holes on the boards were drilled incorrectly, so I logged a return on the 30th of January 2025. After a week of no feedback, I sent them an email with no response and made numerous calls the call centre consultants were unable to help, they kept on telling me my query will be escalated and someone from the courier company will be in touch soon. The courier came to pick up the tv stand on the 20th of February 2025 and I still haven't received communication from Makro as to when I can expect the tv stand back or my refund. On their website they say a refund/exchange takes 7 -14 days but I've been waiting for almost a month. I'm extremely dissatisfied with the level of service provided, you can do better.
