Rude chashier - Consumer Complaint for PEP STORES

I'm really not happy about the lady Zinhle who was helping me, an error happend as she was processing my cash send transaction, and she spoke to me like she is speaking to a 7year old and said "now you made an error and I have to start afresh, your ID" then she took another customer behind me without asking me if I ask her y is she doing that she said " I can send you somewhere else if I want" she never apologized the way she disrespected me I'm really not happy she goes on and tell me That the money I'm sending it's not even for pep.. The are so many unemployed people out there yet we get just rubbish service from people who are not willing to help us with pride.
