Vodacom is a sham

On the 19th of May I did a contract upgrade on Vodacom online, I got confirmation that its successful and I got message that it's set for delivery and a tracking order number. I started tracking it and after 4 days of tracking my order on the 5th day on a Friday my order was set for delivery and according to tracker , later on during the day I went on the site to track it and I'm told vehicle hijacked. Since then until now I've been sent from pillar to post regarding my order and the last person I spoke to on the contract department sent an email to the online department and I got cc'd to see what the reply was. A lady by the name of Tracy rep**** and said they tried a second attempt to deliver my order by my address was invalid I rep**** to that email and told her that my work address isn't invalid and if it was why wasn't I called to rectify/ something. I asked her for a way forward and she hasn't rep**** ever since and that was a week ago already. For the past two months I'm stuck with an order I haven't received and clueless about when if I'm gonna get it. I even went to a vodastore to upgrade and I couldn't because the online order is sealed n it can't be cancelled. I'm beyond upset I have three contracts with the network. I really think the management must review employees like Tracy she isn't doing her job. I'm dissapointed...
