Hawai p8 Epic infinity is a false advert

I went to 4 branches today to get this contract for a hawai p8 on an epic infinity for R999. Finaly phoned cellc on green stone mall had 1 left went there waited for 3 hours just to hear that it was a mistake from them even thoug east rand mall knew about the deal just no stock. The deal is now a while on the internet but no one in head office want to work or do something about this
