If the money fund does not arrive, you can first consult the platform that investors can buy and ask why it has not arrived. Under normal circumstances, the money fund T+ 1 trading day can be received. If the purchased platform does not solve the problem for investors, investors can consult the fund company that purchased the fund.
If the fund company still does not solve the problem, investors can complain to the fund industry association. But in most cases, there is no shortage of money funds, usually because of weekends and holidays.
