Permanently Out of Stock and pathetic service

So it all started the 1st of September, I was due for an upgrade and very keen for it! I completed my Upgrade online and was told there is no stock of the phone, but stock will arrive very soon, so went ahead with the upgade and not take another option since I would not wait to long. I checked up on the upgrade to hear stock will arrive by the first friday of the month and I will have my phone in three working days. The friday i asked if stock arrived and thy said no, stock is scheduled to arrive on the 15th of September, 2 weeks after my order. I took this calmly and waited till now, but now i'm being told it will arrive by the end of the week, next week at the latest.<br> <br> This is pathetic service! How can the date change every time it is supposed to be delivered and how is it impossible to forecast? I moved from a different service provider to Vodacom for this?
