false advertising and lack of help

Good day, I have app**** for two black friday contracts online for nokia 8 sirocco on special. This i app**** on friday and saturday morning i got a call and explained them the lady said she will process the second and the first one is approved. so i waited and waited and called monday no one answered for 20 mins and then called today so they basically put me through 5 people 3 different departments and no solution, why would you advertise if you cannot deliver , why would you advertise false offers, i am really ****ed off and really would like to take up with adverti*****t authority for advertising false ones.
