Bad product & Service

I bought a Milex Hurricane air fryer on the 21th Nov 2020 at Homemark N1 City from salesman Colin. when I unpacked there was 3 items missing. Went back to the shop spoke to Colin. He promise to call the Manager and get back by Monday 23rd Nov. On Wednesday I had to call again to find out what's happening, ones again lots of promises he will definitely call me by Friday to give update. Saturday 28th Nov I went back in he again had a lot of excuses why he could not phone. he gave me 1 of the missing items. But couldn't give the other 2 Items. He got very agro we I request him to get his manager to call me. Also told me that if I'm not happy with it I must return the air fryer and he will refund me then I can go and find it someplace else. This is the 2nd time I bought something from Homemark and both times had to return the item due to bad product and service
