Bad service and attitude from senior managers

On the 12/12/17 I bought a cell phone at Totalsport in Musgrave, when I got home switch on the phone it froze for 2 hrs it was not switching off I had to remove the battery. Monday went back to the store as the contract says any problems bring it back before 7 days,to my suprice when got to the shop they refused to change the phone because they not sure what i am saying its true,will send to the technicians, but when u purchasing u get told a different story,store manager is Selina very useless and her manager Ashley his ego is important than customers,I think he remember the reason his employed there, to make a different he was arrogant. I wil make sure other customers are aware of this false information they give to customers .very annoyed,haven't even use the phone but its gone for repairs. That problem should be between store and supplier I am a customer they should replaced my child's gift.
