Quickseller and
macbook-air.They both have the ability add your transaction to the list of transactions that F2Pool will confirm soon. They may ask you to make a separate payment of a small fee to compensate for the fact that your fee isn't high enough.
You also may want to try using the transaction accelerator at ViaBTC.com (which is free, but limited to a total of 100 transactions per hour). If they've already reached their limit this hour, you can try again once an hour until you either make your request before they've reached 100 transactions that hour or your transaction is confirmed.
