Online upgrade worthless and time waisting

<p>Did my online upgrade 15 December 2016, in January 2017 still no device received. I went to a Vodashop and they could not help me! Phoned the customer service of Vodacom and held on for an hour, still nobody who can assist me! After a lot of phone calls, someone told me to send an email to Vodacom admin to cancel my online upgrade, which I did, until today the system still shows that the upgrade was not cancelled!!!</p> <p>Really very poor service from Vodacom!!!!</p>
