Ridiculous telephonic service

Well i'm due for an upgrade 25/08/2015. One of the Cell C direct consultants contacted me to ask if i'm interested in upgrading on 24/08/2015. I said yes and i would like to have the Huawei P8 everything was fine and finalized. The next day i contacted them and i was informed that the phone was out of stock (why wasn't i told when i ordered it) i then decided to phone around to the stores and decided to take the LG G4. Before i went to the store on 25/08/2015 i cancelled the telephonic order which i was confirmed was cancelled. When i got that cancellation i went to Golden Acre to get my LG G4. The store assistant (Timmy) assisted me very well i was impressed. then she told me that the system won't allow the upgrade due to the cancellation being processed. I got on the phone with Cell C direct where i was then informed that the cancellation takes 48-72 working hours (why wasn't i informed about this from the beginning!!!!!) i am upset with the fact that they weren't transparent with their processes. This is really pathetic!!!!
