Makro has just lost a customer in me so disappointed

Well after I sent my review they called my mum and they said no the melrose did not come from them they dont even have it in the store, and my mum ask how what do you mean cause we have proof and everything then they said oh it's a mistake we must send the Order number on an email and send the items as PDF we did all that and that was it. Till today nothing is happening, I sent a text on their WhatsApp about the same issue and the lady Boniswa said I must return the things by my self to the store after I asked her as much as they are delaying with picking them up they will get spoiled and I told her that I bought online they should come take the same way they delivered them and she just ended the conversation like that with no other words but return it to the shop
