No Invoice provided for Makro Online Purchase

I purchased an item online on the Makro website on 05 February 2019. To date I have not received an invoice for this item. I have tried calling the Makro call centre to request an invoice but I gave up after holding on for a long time. I have e-mailed Makro online support twice - on 11 February and 14 February - to request an invoice and I have not received any response whatsoever. The print functionality on the online website does not work either. Like every other online retailer I have dealt with, an invoice should be e-mailed to the purchaser by default as soon as payment is made. Really poor service from Makro. I doubt I will be making use of this channel in future.
