Your tx has very low fee. To accelerate it on pool they ask 0.007 btc fee, but they ask to pay forward.
Maybe it not worth for you.
Your tx may confirm only if some pools mine it or if drops and exchange or sender send your bitcoin again if you not want to pay.
These paid transition accelerators do not work and you are only paying someone to do the exact same work as the frendly poster mentioned above.
Save you money and do it yourself and let this be a lesson in BITCOIN txt fees.
