You owe them absolutely nothing. I don't use coinbase so can't say exactly whats going on but there's also no way the transaction fee for sending it would be that high either (although coinbase is a rip off from what I've heard - but bitcoin is a rip off full stop tbh it will always cost a few extra £'s).
I've done all my buys with bittylicious and electrum wallet, the buying fee on bittylicious are more than they where a few months a go especially on smaller amounts but it's been easy sailing for me :)
Good luck mate, don't panic and don't give in! don't let bitcoin win! :)
