Vodacom wont honor upgrade

My contract was transferred from Nashua Mobile directly to Vodacom, in November 2014. I recently called to ask when I would be due for an upgrade as I had expected an upgrade notification but never got one. I was informed that i am due for an upgrade at the end of November 2015, but could do the upgrade from the 1st November 2015.<br> <br> I called the upgrade center (***) on Monday the 2nd November. They informed me that my number was not in the system and they hung up. I called back several times and was put through to various depts such as the billing dept, the marketing dept. and a dept called 3G. <br> <br> No one was able or willing to assist. I called back and asked to speak with a supervisor. I was put through to Maria, a team leader at the upgrade center who told me that they will not upgrade me because I have been transferred to a new system. I was also informed that I could not go to the Vodacom shop because they also could not help me. <br> <br> I have a contract that was sold to Vodacom that states I am entitled to an upgrade every 24 months, but Vodacom will not honor that contract. Between Nashua Mobile and Vodacom we are just getting *****ed.<br> Nashua ***<br> Vodacom acc NM122065-6
