Money was withdrawn but has not yet been credited

I have withdrawn more than 37,000 dollars from February 10 to February 22 this year. Parts of them were credited in the first two months. However, from April 13th to now, my card only received RMB 5,000 once on May 14th. So far, a total of RMB100,000 has been received, and about 150,000 yuan has not been received. I call the platform customer service personnel every working day, and they always told me that the problem has been reported to the superior and would be processed as soon as possible. I send an email to the platform every day, but the platform has never replied to me. I don't know what to do now, so I decided to expose the platform, hoping that no more customers will be deceived by such a platform!
