bro is brother did a scam with me, after placing the order he contacted me on WhatsApp and sent me the account number, and I sent him 1500000 lakhs. As soon as he received the payment, he started calling me repeatedly and disturbed me. The time finished and the transfer notification button was not appearing. Now he has blocked me from all places. Please tell me any solution, I have been scammed big time.
