Bad service at rosebank mall vodacom

Firstly I have been to the vodacom rosebank mall a couple of times to buy my phone, collect it & recently to block my line & get a sim swop. The attitude of the employees is unfriendly & unwelcoming. They ignore the customers, sit & chat to each other or walk right past you while you stand aimlessly in a badly designed store. As a customer, I have no idea where or who to go to when I walk into this store. This week my phone was ******, & I preferred not to go to this store but apparently they were the only store that had the imei no. - advice from another vodashop. So next day I go to rosebank only to be told that they are offline. I decide to block the no. & phone on 111 using a friends phone. Again today I go get the sim swop, which was apparently successful until I got home & realized the sales consultant didn't give me the card with the sim pin/puk. Again I call 111 &get the puk. After rejection of puk, I call 111 again, where the consultant informs me that the sim swop hasn't been done on my no. & that I been given the wrong sim. I'm so annoyed. I've been sent from pillar to post,paying for parking, standing in queues, waisting time for simple procedure. Thoroughly unimpressed
