No Feedback Regarding Set-up Of New Phone

My new phn (Samsung S4 Mini) was set-up in store in Nov '14 (Vodacom 4U Store HILLCREST) and due to an incorrect setting, my phn was on WiFi Hotspot with \allow all devices""; handed him a letter I drafted out with my complaint dated 22/01/15 and insisted he requested Data Itemised Billing on my behalf from the tech dept and view his in store camera system; so that he can see that the lady that assisted me on the day that my phn was set-up; had not set-up my phn in a correct manner. Mr Soogrin signed for my letter I handed to him;promised he would view the video footage in store and get back to me with the DIB as soon as he gets it. I have sent him 3 e-mails since and he just does not read my e-mails or reply to me at all. """
