Disappointed by your Mall of Africa Staff

You have the most *********** and rude staff ever. This is my second time being disappointed by your Mall Of Africa staff. I bought a laptop and struggling with activating Office as the voucher number is not working. They cannot even call their own service provider to fix this and a very rude Sabelo Mathebula told me I need to come up with a solution. If this is not fixed by next week I am bringing back the laptop, I cannot be paying for something I am not using. Do better please.
