Any ETA on the burning of the unsold tokens? Not that it's super important right now, just wanted to know when we can expect it (days, weeks from now?)

As soon as reddit & sig campaigns are paid + a few problem orders resolved.
We have a few orders (a few somewhat large) where we successfully received BTC payment but are having trouble contacting the buyer to get a valid NEBL address. I want to try and contact these buyers several more times before I burn the tokens they paid for.
I am assuming they will be refunded and the burning will commence if they are not reached correct?
