**** and bull n1 city bad service

I was last week saterday in **** and bull n1 city. Bought 3 packs cigarettes and 2 jet flame clipper lighters. The 1 lighter is problematic and decided to return the faulty lighter. I did not receive a invoice on purchase and on my return of the lighter the did not want to exchange although I offered to pay in the difference. I am a regualer client of them and out of anger I told them they can have the faulty lighter and left. They did not even try to assist.. I will never return there again. Disappointed.
