3 week wait... still no phone

After finding the Z2 at an affordable price I decided to upgrade. Called my local MTN outlet (because the MTN website is hopeless). I asked for the phone, was told it would take 10 days to arrive. Initially I was frustrated that it would take that long and feared I would lose out on the deal. The store employee assured me I would get my phone. Well its been three weeks, no phone. I have to call them every two days to ask if it has arrived and frankly if I could find the phone at that price ANYWHERE else I would change carriers tomorrow. What the hell is wrong you. Why advertise a phone you simply CANNOT SUPPLY!?!?!? Disgusting, if this is how you treat customers imagine how you treat staff, no wonder they went on strike. I want my Z2 as advertised. I ordered it 3 weeks ago.
