Upgrade

Trying to upgrade my phone for 2 weeks and because I am on the new system the istore need to send in the papers to vodacom. I have phoned and was told that it normally take up to 3 days and that I won't be able to do anything as the store where I did the upgrade need to escalate. Which they have done. Everytime the istore phoned they say we need to escalate but nothing happens. This is by far my worst experience to upgrade yet and after almost 2 weeks I am thinking of maybe cancel my contract and go to a different supplier. I have been loyal to vodacom for more than 15 years.
