I paid a SparkX withdrawal fee and was then blocked

I was directed from a WhatsApp group to open a SparkX account for USDT trading. I followed signals and was encouraged to move through increasingly expensive trading-plan tiers.

When the account showed a large balance, I was told a 20,000 USDT payment was required before a withdrawal could be approved. After I paid it, the group administrator blocked me on Telegram and I could no longer access SparkX. My reported loss was $328,800.96.
