Accidentally sent USDC from Matic Network to CB

I accidentally sent all of my USDC from my Matic Network Metamask to my coinbase pro account. The money never arrived. I have submitted 4 coinbase support claims but they are not going through because when I submit the claim, the form is not recognizing the matic network hash and thinks that I am entering it in wrong.

Can’t find any Matic support desk. This forum is all I’ve found.

I’ve also contacted Metamask but they said they can’t help. Don’t know what to do. Any help would be appreciated.

Hi. Please raise a ticket at the Matic Helpdesk at
