In Feb 2018, do they asked to submit? or you did by yourself?
there could be a misunderstanding, one of my friend when applying for refugee did a biometric, then he got married. these days they asked him to submit biometric and to wait for an appointment for that but after some time they just simple updated his biometrics,
this is not the same situation but overall it says that sometimes they go by procedure then realize that they have already what they ask
you should somehow to write to Ankara VO about documents, i can provide they have these documents, just remind them,
the email below contact them

good luck,
