Some miners still do full RBF, meaning that there does not need to be any opt-in signalling. Such an RBF transaction is basically the same transaction but with a higher fee, so one of the outputs will be slightly smaller.

Your transaction fee is fairly low. You paid a fee of ~65 satoshis/byte. The current recommended fee is ~120 satoshis/byte according to http://bitcoinfees.21.co/.

You have a few options. You can wait for it to confirm, wait for it to drop from the network and resend with a fee, attempt a double spend with a higher fee (RBF transaction), or ask a miner.

If you want to do the third option, we need to know what wallet you are using.

For the 4th option, you can contact the users macbook-air and Quickseller. You can also try using this tool: https://www.viabtc.com/tools/txaccelerator/
