Help me understand if I am being lied to by Circle

Hey all,

I'm not much into crypto myself anymore but found myself in a situation where some technical expertise is needed. A friend of mine and I used to do business using the Circle platform (known for USDC) to accept crypto and fiat payments.

This year we decided it wasn't bringing enough profits and closed it. To settle some invoices and taxes my friend wired me 2 ETH to my Circle account using their internal wallet address, which is created for each user with an account. After the transaction was settled on the blockchain, Circle came back to us saying that they only accepted USDC and something else in that wallet. We requested Circle to reverse the transaction and send the money back to us, to which they responded that their infrastructure is not designed for such things etc etc. Long story short, they keep giving me a runaround about the funds and I cannot get it.

Does it sound right to you? Can they really not access these funds in their wallet and send back to us? I feel like they are trying to keep the money
