Complete neglect in customer service

I have a few Vodacom cell numbers on my business contract which is in the name of my sole proprietor and has been ever since I can remember. I requested a transfer of ownership from my sole prop, into the name of my close corporation. Sent all relevant docs by email to Danie Coetzee on 3/11/14 and had no response. again on 5/11/14 no response. visited store spoke to Lindy Lee , she gave me her email address to forward docs but she had given me a wrong address. Spoke to Danie few times on phone he insisted they'd sort it out, still nothing. Visited store again in January, spoke to manager Lucas, told him how really upset I was & that I'm going to throw my toys out of the cot if nothing happens this time. he mailed me fews days later requesting banking statements from me. i emailed him banking statements around mid January. Still to date no action whatsoever. no response, no feedback. By the way close corp is an existing business since 1994, dont understand what the excuse is. Phone just rings when you try to call.Have all emails as proof!!
