Update: Phone call with “John Grant” from block analysis no real answer

This is an update to my previous review about Blockanalysis and their connection to wallet swiftbloc [trustpilot +2]
Today I called and spoke with a man who introduced himself as Mr. John Grant. I asked him directly about my complaint that I submitted through their website and whether he had any answer for me. My voice was a bit raised because I have already lost my bitcoins and additional ETH after following their instructions, and I am still waiting for a solution.[trustpilot +5]
His reply was: “I don’t know what answer you want me to give, people pretend to be us,” and then he ended the call instead of helping me. He did not offer any investigation, refund, or concrete explanation, and he tried to shift the responsibility by saying that others “pretend to be them,” even though I used the contact details from their own website.[blockanalysis +3]
For me, this behaviour is not professional and does not match what a serious investigation or recovery company should do. I again warn others: be extremely careful before sending any money or crypto to services like this, especially if they ask for upfront payments or use excuses about “verification” and “impersonators” instead of giving clear answers and real help. I am continuing to report my case and share my experience so that other victims can be aware.
