BAD CUSTOMER SERVICE

I placed an order through Yumbi to collect it at the above mentioned branch @12h14, 12h35 I get to the store to pay and collect only to be told by the cashier that the supervisor Julia Mnisi instructed him not to process our with what reasons i don't know. I asked for her attention only to refuse coming to address the matter, this is not the first time that she has given me and my colleague's bad service and always are orders get mixed&dsnt expect us to complain. What right does she have to instruct the cashier not to process our order as customers. Right of admission is reserved at the store but it's totally wrong to treat customers they way she. She needs to apologise to me and be given a warning. You do not behave like this as a manager. Our order was only captured at 12h53 and was only ready for collection at 13h20. On wednesday the 27th and 28th of March my order was also incorrectly captured , when I got to the office i called the store to notify them and the very same woman gave me bad attitude. I am really tired of being treated like a nobody, is she doesnt want to serve customers then she's in the wrong environment
