If you send payment to poloniex without a payment id, they can't detect your payment automatically. Now they can try to identify your payment manually, but there is no guarantee that they can do it. There is a possibility (it is just for example) that somebody tells to poloniex that it was he who send this transaction,  in such case poloniex can't detect who is really send it (remember, that BBR was created as non-linkable and non-tracable currency). That's why it is very important to use payment id for such transfers. Wait for poloniex reply now, they are the only people who can help you in this situation.
