Even so that's weird, Usually after you successfully accelerated your transaction on viabtc, Your transaction should receive at least 1 confirmation in no longer an huour but its past 4hours now (basing on the time OP posted this) and its still unconfirmed .

And so I tried entering it on viabtc, It says transaction not found, Are you sure that you successfully accelerated it on viabtc OP?
It's probably because both of the transactions have low miner fees, It's been days since the transaction has made the best option is to just wait for a couple of days and wait for the network to forget OP's transaction .
Alternatively OP can pay on
https://pushtx.btc.com to confirm your transaction .
Note: They don't charge cheap
