Nova Global AI Compute Investment scam with fake high returns

Hello. I would like to report a suspected investment scam involving Nova Global AI Compute Investment. I invested UGX 90,000 and UGX 180,000 and was only able to withdraw UGX 15,000. My account now shows a balance of UGX 120,000,000, but my withdrawal requests have not been approved. I believe I may have been defrauded. I have screenshots, transaction records, and communication details available. Kindly advise on the next steps and any assistance that can be provided. Thank you.
