Mortgage complaint — Selene Finance LP (GA)

I closed out my mortgage loan with Selene Finance when I sold my former house on XX/XX/2018. I was told by the closing attorney that Selene Finance would send me a check for the excess money in my escrow account within 20 days of closing. Selene Finance has confirmed that there was approximately {$4000.00} in my account but they have not sent it to me, despite numerous attempts to contact them.
