No stock, no feedback, overall horrible service!

I took out a new contract the 15 Jan 2016. From there on it was almost a 2 week waiting period for the credit vetting. The contract was approved and from there on I have been waiting for stock for my new phone. The worst thing is not the waiting the worst thing is the service they provide. You can't get hold of anyone over the phone, if your lucky enough to get through the person you want to talk to is always busy with a client, so obviously that new client is much more important than the one on the phone who is already a customer. New customer is priority and then after that no service will be provided to you. I was told 10 times that someone will phone me back no one ever does. I cant go into the shop everyday as I am working in there retail times. I eventually got a email back the other day saying they will search for a phone at different branches, why cant you do that from the beginning. This was on the 4th of Feb and from there on I have heard nothing since. Emails goes unanswered. I now requested that I want to speak to the manager but nothing has come from that either. The manager also probably doesn't care that's why its going there as it is. I have been patient enough
