Missing Solana Withdrawal

I had made a withdrawal of 39.07 Solana from Bitstamp on Jan. 3, 2024, 12:22 AM.

Bitstamp says the hash is as follows:- 

4GXGEoobvNDsn8wJ82wDYXDNrt9XPNJCPYYLBHQsh33PVkMaRHTopH5tz4JPvD8ybMHstvGVAhaNCgSbzUJhtBZD

The destination wallet:-

7FC1T8L2zKRN89ar6mQ9uS9ZaJ4D2ed7qEYX5VHCseNa

Transaction ID: 313235079

But the solana never arrives at the destination wallet. Please urgently advise and revert. After not having received responds on 2 tickets (one email, one in-platform) I tried calling the customer support from the numbers provided but I only heard a machine saying that they want me to give customer rating and then hang up.

I really hope I need not escalate this with the regulators. I would appreciate an urgent resolution.
