I hope you will be able to reach them and have the issue sorted out. But from a bitcoin perspective, your transaction is OK.

The transaction 8772fd17e783b9e787e29f294ab0815b02f2b44e3dbcbb3d60d6799d72f5586a, which was posted by was posted by mpgalloo, was confirmed yesterday. You can look it up using a blockchain explorer, e.g. https://blockchain.info/tx/8772fd17e783b9e787e29f294ab0815b02f2b44e3dbcbb3d60d6799d72f5586a.

However, maybe that transaction wasn't yours but rather something mpgalloo happened to post about in this same thread. You mentioned the address 1HHWh5HxmCR9441nK2Q3gtrpGJCCuoKkYm, the date 20 December and the amount 490 dollars, which would be approximately 0.03 bitcoins. This matches the transaction 8e081ae277565ffeda7b383c124069e8a6e8ad9d20b602620904c22f847d1d2a, which was confirmed on 20 December already.

So with apologies for the non-specific reply, I conclude that both transactions have been confirmed. You can look up yours using a blockchain explorer, e.g. the one I mentioned above.

Your  transaction was confirmed yesterday. I hope you’ll receive your funds soon.

Sounds like he might have gotten scammed, or fell victim to slow bank processing times over holidays and New year's. The address 1HHWh5HxmCR9441nK2Q3gtrpGJCCuoKkYm did successfully transfer and confirm the 490$ you speak of on the date specified. You need to contact "coinify"
