Cant upgrade with Vodacome

<p>I qualify for an upgrade since March but there is a error on vodacom system that prevents me from upgrading. Phoned over 12 times last 3 weeks trying to sort it out. The second last time i phoned i was informed that there has been no querys logged on my number. every consultant i speak to promise me either to phone me back or that the problem will be solved in 5minuts/ 10minuts / 24hours / 5days. no one hase ever phoned back. They all refuse me to speak to a manager. I dont know what to do anymore. I want them to sort the problem out so that i can inform them i will not upgrade or use vodacom ever again.</p> <p>I have been a client of Vodacom for the last 12 years. iand i will not waste my money on them anymore</p>
