Pathetic service from Vodacom

The below incident was reported on the 17th of Feb... i was advised a consultant will contact me.. To date no one has bothered to contact me!!<br> <br> I called the Vodashop to enquire if i could do a premature upgrade and was advised it is possible and that i needed to call some 082 number. When i called i was advised it is not possible. I would like to know why is it not possible? My upgrade is due in June. Only 4 months away.
