Repairs taking forever

I am very disappointed at the service i received from orange/za. on the 1st of July i received a cellphone i bought from orange, within two weeks of using the device it just died, it didn't wanna switch on or even charge. on the 15th of July i then took it back to sunninghill for repairs. on the 16th they acknowledged my return. now its been way over the days period they promised it was going to take them to fix the device. Every time when i call them they always tell me \ we going to escalate the matter". if this is how customers are treated at orange SA i am never going to purchase anything from you guys"
