Makro - failure to follow COVID 19 Regulations

Got to the store on the 15/12/2020 to return the Milex Air cooler which i had purchased 7 days prior. The device was faulty. Whilst in the que to return the item i noticed that there were 2 other customers with the same product having problems. I spoke to the teller and she said that she would have to book the item in for repairs which would take 6 weeks to be sorted out. I then querried that if they are going to fix the device would the device be sanintised and if would get a certificate for such as being a device that blows air could be a health hazzard with regard to COVID 19. She then refered me to the manager to assist i posed the same questions to the manager and he said that they would not be able to sanitise the item. I then asked the manager if he knows how COVID 19 is spread and how it works, The manager then very abruptly asked me to explain. After exchanging words i asked to speak to the senior manager. The senior manager came out and walked into my face, literelly 10 cm from my nose. the attitude that he came in with was as if he was comming to assault me. i asked him to back up from me as he was in face and refused to do so. I then took two steps back and asked him to assit. i expalined to him my issue and he said he could not assist. I ten walked out and left my device with and told them to keep it as i could not take a health hazzard to my family. i have logged calls , with regards to this complaint and 6 weeks later no responce.
