Upgrade online sucks

I did an upgrade last week and i received my device 20/02/2015 over the weekend i discovered that my battery drains fast i call the online team and they advised that i need to go to my nearest vodacom branch and let them test it. I did and the battery were faulty, i called in again the person i spoke to did not have telephonic manners at all but said the device will be send back and the contract will be cancelled, i then thought why would they cancel it cant they just replace it? I called in today and a lady i first spoke to said they should have done that. I was placed to 5 different people and with all i had to explain my problem and finally i got to a competent consultant named Linett she assisted me fantastically and she was friendly and called me back twice to explain what will happen THANX LINETT.<br> My problem is however not with her but with the fact that i have to now wait 2weeks for a new phone, you guys make it look like its my fault the battery does not work! I ordered a new tv from takealot and it was faulty they replaced it then next day and picked the other. Why cant you guys do the same???? Vodacom i am truely disappointed S3-8XY1F-FK
