Premature Upgrades

Hi I tried to process a premature upgrade with vodacom. Only to be notified that the terms of a premature upgrade have been changed. When checking on the vodacom website I got confirmation that I could process a premature upgrade and that I would be contacted within 24hrs . No one from vodacom contacted me it has been 48hrs.<br> <br> When I call I'm told that the rules have changed and I don't qualify for a premature upgrade, the rules were changed last month. If these rules have changed why is the website still operating on different rules.<br> <br> This is also the second time I've been told someone from vodacom will contact me , and have not received a single call from vodacom.
