SO an update.
The Girls father has sent an email to my Boss at the other shop, Stating he knows i had no ill intentions, He simply didn't agree that i was using the shop as a way to make my own money, Also didn't believe that i had an operation the day before and required home collection, He though it was just a way to keep it away from the shop.
He wasn't happy that i was texting details of the repair to his daughter and though i texted first it was simply to tell her that there was no white screen available. (she gave her number as the point of contact)
He Expected that i would now be an Ex-Employee (Yea right), But is willing to meet myself and my boss at a location specified by my boss.
He says he has done some research into trading standards and because there was no written agreement between myself and his daughter it means that there was no service provided and thus he has no reason to pay for it. (so the ipad was fixed by magic yea?)
So... Seems he simply wanted me to get in trouble and get a free repair.
I have asked my boss to reply with a date and time for next week, and to ask that he brings the ipad for inspection by my boss. If he doesn't play ball i will simply grab the ipad and leave the meeting place with it until he pays for the repair. I have spoken to a solicitor and they have advised that I'm well within my rights to remove the screen i fitted if he is refusing to pay. and that's what i will do if i get my hands on it.
So screw all you GD pitchfork holders.
