Terrible Service

Went in two weeks ago to get my screen fixed. They told me it would take to weeks because its an S5 and it needs to be sent to the headquarters for the parts. Two weeks later I walk back into the Samsung store in Woodmead. Where I am informed that my phone isn't ready, and that I should call Powercare. I call Powercare and to my shock, I am not in the system, they can't find my phone. I of course call Samsung and ask for my Reference/Job number, the lady tells me that she hasn't given me a job number because the system was down on the day I booked my phone in. That was 2 weeks ago, TWO! And she STILL hasn't logged in my phone! <br> <br> Why?
