My presumption is that there is a third person here as an impersonator using a telegram. Scammers contact both of you at the same time.
If that doesn't bother you @shasan, I'd like to hear a chronological story of your friend's first act of contacting support especially when he got in touch with that "support" telegram, who contacted first?
Has he written his complaint somewhere publicly with account details (before payment is marked complete)?
