Waiting too long for phone delivery

I took out a contract online on 21 July 2015, I missed the confirmation call the next day. They only called once and then gave up. I had to call the call centre twice before I got someone to do the confirmation call which eventually happened on the 24th. I was told my phone would be delivered on the 27th. <br> <br> On the 27th I called and was told that they do not know when my phone will come and there's nothing they can do about it. <br> <br> On the 28th I called again and Kim said she will call the warehouse and get back to me in half an hour. Two hours later I am still waiting for feedback and desperately needing the new phone as my old phone is broken.
