No phone for almost 2weeks

I bought a contract for my daughter on the 8th Dec which i sent back due to the device being faulty - I was told to wait the device will be replaced the contract cancelled and I will be able to take our a new contract within three days of cancellation. The contract was then cancelled and i reapp**** for a new contract on-line which I was told was not captured on the system due to technical reasons. I called the on-line sales office on 5January 2016 and got through to a SHARNEL who sent me an email with the Reference Number: ***6. She assured me that they would call me back as this is a replacement and shouldn't take long - NOTHING. I again called the sales department and was then told this was not the case and then helped by a Shane who eventually got my application sorted - Since Wednesday the 8th I have been calling the call centre to await the confirmation team to call me When I called on Thursday afternoon again I was told that they tried to ring me on a 078 number which is not my number at all. I gave them my correct details. I received a call on my correct number which I answered and the call was dropped. I have sent an email to Customer Services ans still no reply
