الجوال مقفل وبحاجة فتحه من قبل الدعم

translated from Arabic:

I bought the phone from someone and he told me it doesn't have iCloud.

Indeed, I entered my iCloud after a while, the phone was locked, and I was asked to an iCloud that does not belong to me.

Please help me unlock the iPhone, because the person from whom I bought it does not want to return the device
