Vodacom/Elite Mobile Incorrect Hanset Upgrade

my wife was due for a Vodacom upgrade, we were contacted by an Agent by the name of Naidoo(surname only) from Elite Mobile, after many telephone conversations she finally agreed on a handset, the Apple iPhone 6S 64gig in Rose colour, which was confirmed on numerous occasions. when the phone arrived we opened the box only to find they sent the incorrect handset - Apple Iphone 6S PLUS 16gb in space grey, with no new SIM. <br> we contacted Elite Mobile the next day and notified them of the incorrect order requested for the upgrade to be reversed and handset collected, as well as why now do we have to go into a Vodacom store for the SIM upgrade, if this was explained we would have rather just gone into Vodacom directly and done the whole upgrade, we never asked to be contacted by Elite Mobile. we are still waiting for the handset to be collected and as a result she is unable to proceed any further with a new upgrade. cell *** Acc S***, Elite Mobile Order U***. how do we proceed from here? we have been waiting now for 2 weeks. can you address on behalf of Elite Mobile?
