Worst staff and service ever!

I’m currently at the Midrand mall shop again the people working at the buy shop do not have name tags and they refuse to give me their names. It seems the one person is called Ebeniezer. I have logged a complaint previously regarding my machine which they lost bolts on the machine. I have sent WhatsApp text to verify if I should collect the machine and the person on the WhatsApp line said yes. Then when I got to the shop the person who was assisting gave me an attitude because I was telling him was said on the WhatsApp line. This shops staff feel so invisible and have a bad attitude with no customer service. I cannot be having the same experience all over. I want my machine it’s it’s original form.
