Review Terrible terrible service of Makro

Bought a Swan 2.5l Air Fryer on 18/12/2019 online from Makro Amanzimtoti but has never received delivery or got any service or replies of my 50 emails I’ve sent them. I had to send the item back to Makro and still waiting for a reply or a refund. I have asked for a refund but nothing is happening nor are they responding to my emails. Makro is the worst to order stuff online as you don’t get any service or delivery from them. What can be done about this? Maybe the boss or owner can sort out my situation? Please help!!!!!!!
