No response on upgrade not arriving

I did an upgrade on my contract for a new device on the 26th January with Luan at Autopage Brooklyn.<br> I have received absolutely no indication as to when I will receive the device. I have called many many times and the phone is never answered. Only once have I had a call answered and I was instantly told \we will call you back"which has not happened. I have emailed him and I have received no reply. I have been back in store and was told they had an error with submitting all their upgrades???<br> <br> I will be charged for the new device without having received it.<br> I request urgent attention to this issue."""
