is this a scam? anti terrorist clearance code

if this is related to the scam you posted above, they will not refund your money. They only want to keep you quiet and make you believe they will. If you paid with a credit card or bank T/T transfer, then they are trying to run out the clock so you can not dispute the charges with the CC / T/T company. If you used a CC or T/T to pay the scammers, dispute the charge now and there is a very slim chance you may get your money back. Note I did say "VERY SLIM" chance.

As with the scam above, it is very likely a fictitious (fake) name they are using, or impersonating a real entity that knows nothing about you.

You would have to give more information than just names. Email and web address(es), physical locations, and people's names can get much more in depth than a name can.
