6 Weeks turnaround time on Warantee goods

Received my Sony Experia Z3 in December 2014, less than 4 months later the phone overheats and subsequently does not reboot again. <br> <br> My service provider received the phone two weeks ago, I have not had any correspondence since then. I take it upon myself to contact Ingram Micro, they are repair centre Autopage uses. They have not informed me that the phone will take 6 weeks to be repaired and or replaced. <br> <br> My question is, this phone is still under warrantee, why not replace it? I still have to pay for my contract, even though I am unable to use it. <br> <br> Upon asking this question I have the reply that I can use my old phone, sorry this is a matter of principle! I don't pay for my old phone! I pay for my new one, I did not brake it! it is your responsibility as a service provider to ensure that the equipment I received from you works, from the beginning of the contract up to its completion.
