Material missrepresentation of Samsung dual sim cell phones

Material missrepresentation I bought a Samsung galaxy J7 Pro for cash online on the Tfg website at the Hi store.It is a dual sim card phone released by Samsung in 2017. I received the phone but to my surprise they sent me a phone that had the one sim slot blocked.I returned the phone as this was not what I paid for.I was informed that the website didn't state that the phone was dual sim,but it didn't state that the one slot was blocked either! This for me is a factory default that causes me to return the phone as my intent was to purchase a Samsung phone that comes with two sim slots,as per cell phone specs by Samsung,why was the fact that the one sim slot is blocked omitted. Tfg and network providers why would you alter key functions/specs of a branded cell phone and not advise the consumer? Why missrepresent the Samsung galaxy J7 Pro by ommiting the fact that you blocked the one sim slot?I will not be bul**** into keeping a cell phone that I cannot make full use of
