You will need to call customer services: The numbers to ring are 150 free from a VM mobile or landline, or 0345 454 1111 from any other phone (chargeable as standard UK landline phone no.).
As to the cost - who knows - as you have admitted to the fault being due to an accident by your wife it is unlikely to be a free replacement. Do you have accidental damage insurance under your home insurance policy?
