Ackermans Witbank staff is terrible.

I have just been to your Ackermans Witbank branch, Shop A5, downtown, and WOW the level of incompetence and indifference is appalling. I bought 3 cellphones in May with promises that I will be able to use international sim cards. The two cellphones are receptive, but one cellphone isn't. I went there to resolve this and your stupid ugly and shapeless assistant Mandisa Masango didn't even bother to listen to me. She said, with attitude that she doesn't make mistakes.... furthermore... she turned to the cashier Mxolisi and asked him why she was called. Mxolisi even asked her if I'm not a customer that needs help. That witch said she doesn't know why she was called when she assisted me with the purchase. The manager was then called, who never showed up because they were on a phone call. What the hell do your staff take us for??? I walked out after waiting about 20 minutes for a resolution. Your staff is too comfortable, they lack customer service, especially that stupid Mandisa girl.
