Stay away from Core Croup

I bought a IPhone 6s cash. The phone didn’t even last a full year and it started giving me battery draining issues. After I tried to replace the battery it still didn’t work. I send it back to them and they wanted me to replace it with a more expensive phone trying to make more money out of me. After I received my phone back the screen was damaged. I did complain about it and provided them with a photo showing them that they damaged my screen. Obviously they refused to fix the error. I am so disappointed in people undermining your intelligence and just giving you a I DONT CARE ATTITUDE. After all the emails and struggle I ordered a replacement screen and fixed the screen myself.
