Before a week I bought a iPhone 7 from eBay and I can't activate it. The seller told me that the Apple ID was removed from the device, but after I got the phone the Find My iPhone was activated and the phone asked for iCloud email and password.

I tried to contact the seller, but I didn't got a response. I was scammed. Is there any way to bypass iCloud activation lock on my iPhone and activate it without the previous apple id details?
