NO HELP WITH UPGRADE

I've been a loyal Vodacom Corporate customer for more than a decade, with an average spend of R800-R4000 pm! My cell was ****** during Dec' 2015 and when I went to the Vodacom shop Tygervalley for a sim swop, I was assured I can get a \pre-mature upgrade"end of Jan' 2016 - I'm only due 31 March 2016.<br> <br> Last week I was browsing new phones to know what I want in when I upgrade month end. I decided on the new iPhone 6s Plus"
