ok. i am the sender. i have Exodus private key and blockcain.com wallet private key. so can't do RBF ?.
You cannot.
do u know any recommend person or site to do this?.
A few sites:
https://pushtx.btc.com/https://www.viabtc.com/tools/txaccelerator/https://pushtx.com/Unfortunately, your TX is rather big and it would cost a bit more to accelerate it. This is why people recommends using wallet like Electrum or Bitcoin Core which allows signalling for opt-in RBF to reduce these kinds of situation.
