The customer service refused to withdraw due to they think i was involved in money laundering

The customer service claimed that there was a third party involved in money laundering in my account, so refused to withdraw the money, It is necessary to pay 100% of the amount of funds remitted by a third party before it can be reviewed；and the money could only be withdrawn after passing the review. It is true that my account has a loan of 2000 USDT from my friend on the Internet, but I must submit another 2000 USD for review, which inevitably makes people doubt the legitimacy of the platform; whether it is a black platform that everyone calls it!? The platform claims is being regulated by MSB in Canada and the United States, so through this i would like to know what the regulatory effect of MSBs is. Except regulate the money laundering, also works for regulating investor funds?
