Upgrade order not received

I placed an upgrade order online with Vodacom on Friday, 19.06.2015. On their website they promise free next-day delivery and seeing as I only placed the order on Friday, I at least expected the delivery to be done on the following Monday, 22.06.2015. <br> <br> I sent them emails on Monday, after waiting for the delivery that did not happen, and they have yet to respond to my email. One of their consultants phoned me, but I missed the call. They didn't try to phone me again, but instead sent an email stating that I did not answer and therefor they are forwarding my query to another department. Till now I have had no further response. No upgrade phone and no response.<br> <br> I have been a contract customer of Vodacom for a few years now and I am truly disappointed with them. Their service has really become very poor. It is no longer what it used to be.
