VODACOM UPGRADE DELAY - NO COMMUNCIATION!!!!

I requested my upgrade on 1st March and was told I'd have my phone, the Huawei P7 Ascend, by the 4th. I received a call on Tuesday (3rd) and was told that the phone would only arrive on Friday (6th) and I would have it by Monday (9th). I had received no feedback regarding this and eventually called on Monday and was told that there is no stock and none was sent top any of the branches and that the staff cannot give me an expected delivery date. I can't possibly understand how Vodacom can operate like this, how do you just tell a client they must just wait! I could be waiting for another 2 weeks or more! Worst of all is that my BIS expired as my contract is now ready for an upgrade and I didnt purchase BIS as I was supposed to have my phone within 3 days! I'm not prepared to buy BIS if I'm getting my phone in a day or so. This is pathetic service from Vodacom, how can you advertise a phone and then just not send stock of it and worst of all not communicate properly with the client! I last spoke to the Musgrave store on Monday and have yet to receive any follow up! I want my phone!
