UPGRADE / WHAT A MISSION

I have been waiting for a week now for someone to update my upgrade. I was called and had to correct the order and i was advised the order would have to be returned to sales to update it, i was then called again to confirm the wrong order yesterday. Now i have not heard anything - why is it such a mission to actually firstly get the upgrade right did the lady not listen or actually care to enter the correct information and then after 2 calls its still wrong
