Hi @Shahhussain 

The only person who can blacklist the handset is the owner or the device and tariff. The person you spoke to has lied to you and will likely vanish. 

This is a common scam and you are a victim of crime. You need to report them to the police.

As for your device EE will not help you as you're not the original owner. 

Never buy handsets from eBay (unless a verified reseller) gumtree, Facebook marketing place etc... guaranteed to be scammed.

Thanks
