BB Torch :: Broken Charger Socket On Phone

I have a Blackberry Torch which has been fantastic.Brought December 2011.I plugged the phone in to charge last night as usual and this morning when unplugging the phone the enitre socket came out of the phone and is now attached to the end of the charger. I phoned Carphone warehouse for advise about the repair of the phone under the warranty and was told the charger socket is not covered under the Blackberry Manufacturers warranty and any problems with the socket are down to wear and tear, which I would have to pay £160 or more to have it repaired.I can not find any warranty information on the internet. Please can you advise if this is the case.The phone is only under a year old and I have never mistreated the phone charger socket therefore I do not understand how such an issue could occur, unless there is a fault with the phone? I also have a blackberry curve for work and had no problems with the charger socket.
