Second hand fone for a fine upgrade by Ackermans gateway

Hi

I would like to make a complaint, I recently did an upgrade on the 31/03/2026, and the people in Ackermans gateway sold me a used Samsung, he first brought out a phone that was already opened and it refused to register, he than again brought out another one that was already open which did register, but upon registering it the Bluetooth was already connected and personalized and the Samsung profile already registered with a name i don't know. The contact already has a name as. Well I want this phone changed and given a new one and compensation for Ackermans breaking the law. Selling me a used phone. I'm very angry about this. My ID no. *** 085 and registered phone yam no. ***
