"The scammer's security is very right. IP is highly protected but during the recovery process we can hack their data and disclose to you who they are. Recovery with us takes 4-6 hours. All you have to pay is the registration fee on Blockchain to enable us to cooperate with Blockchain for a successful recovery. Because without the help of Blockchain recovery cannot be possible."
When you read mails like this, the first thing that should come on your mind is, scam. I have never used any of these services as I’ve not had the course for it but I can tell you for free that this is a 100% scam.
Recovering in 4-6 hours when they haven’t known the context of the job. I don’t think that’s right and I remain of the opinion that you don’t get to pay nothing for commitment but rather, their could be an agreement on what percentage of the recovery that can be remitted as payment.
