I recently made a withdrawal on Poloniex where i simply forgot to add Burst- in from of my wallets address.
This resulted in me having create a ticket on their support forum.
It then took 23 days before i got my first answer on the ticket.
They refunded the total amount swiftly at the end of it all but i must say 23 days without a reply is a rather annoying experience.
Moral of the story is remember "Burst" and you want go through this stress
