Makro online bad after service

I've made use of Makro online for the first time ever on 13 Feb 2025. There were two items om my order (MAK***), amongst others a size 20 x 50 binocular. For some other reason Makro separated the order in 2 separate orders. The binocular was delivered on 17 Feb. Upon receival thereof, I noticed that they sent me the wrong binocular. It was an 8 x 40 binocular instead of the 20 x 50 binocular. I immediately logged a return request order accompanied with a couple of photos. I received a response from Makro to inform me that the Makro team is currently reviewing my request, and I will be contacted within 2 - 4 working days to arrange collection. Since then (17 Feb) I haven't heard a word from Makro. I've sent follow up mails to no avail on the 20/2, 28/2, and 5/3 begging them for an update. I also contacted Makro Customer services on 3/3, who undertook to arrange for the pick-up of the incorrect item. Also, to no avail. This is unacceptable and absolute bad after service. It was not a fault on my side and haven't receive anything like this elsewhere.
