my ghd fell , was working perfect , now one wire not connected from plate,?

Hi - My ghd straightener only 6 monthe old, worked perfect. Dear nephew left it on window sill,fell off and one wire now not connected to iron plate thingy. took it to an appliance repair place and without looking at it told me its stuffed and cant be fixed. Seems easier than that to me (but Im blonde..-dye job mind you)
Im sure they could be fixed - any suggestions -please help
