Delay in repairs

DISPLAY ON SAMSUNG S5 JUST DIED. Took phone in op 15/06/2015. job number DWK*** was informed it will take 7 working days.<br> I phoned op 26/06/2015, 9 working days later and was informed the shop have not received spares yet. Nothing was done within 7 working days and no feedback was given. I feel it is bad management and poor stock control that there is no spares in the shop when replacing screens as their main purpose is to replace broken screens.
