Unprofessional sales manager at Makro Polokwane

Good day

So today I took back a microwave oven that I purchased from Makro In Polokwane. The sales manager Eddy Mdanisi was the one assisting us and at first he didn't want to refund us because he was claiming that whirlpool didn't want to fetch the microwave. We eventually got refunded after going back and forth with him and fighting with him because he was not willing to refund us. Now I just got back home and to my surprise he sent me a voice note speaking about me after doing some research on who I was, calling me rude and all. That is very unprofessional and I will not tolerate such childish and unprofessional behavior. He must stop embarrassing himself and harassing me with voice notes. I had every right to go to Makro and demand a refund for a defective product. Why must he now send me a voicenote whereby he is heard discussing about me with his colleagues and what I do for a living? My personal life has got absolutely nothing to do with your defective products. Expect to hear from my lawyer very soon, I will not be bul**** by your staff members who cannot differentiate between being professional and personal.
