Thanks for suggestions, gonna do that. And yeah, that's the worst part, they are using someone else's reputation to scam others.
I wrote to
Bitrefill and also DMed them on Twitter. Hopefully, they issue a warning now that they're aware of the situation.
I contacted Bitrefill as well, after i stumbled upon this , but seems like their bitcointalk account is offline for a few days now, and nothing so far in their social media. As you said, they should issue some warning to protect their users.
