I would try a resync or something. Probably there just the wallet isn’t registering for some reason. There’s no real way for them to send your bitcoin to keys that don’t belong to you because all they can do is force close the transaction you signed on their side. Which means it is sent to your address unless it’s just stuck in the mempool, but because fees are low I doubt that’s the problem. 

Keep us updated, happy to help if I can. Don’t stress, your coins are very likely accessible, just something not picking it up properly for some reason.
