There are other transaction accelerator services out there. The quickest one i know is on ant pool. Create an account and paste your TXID there: https://www.antpool.com/user/prioritiseTransaction.htm?m=savePrioritiseTx . You can also try Viabtc https://pool.viabtc.com/tools/txaccelerator/ but your fee should have at least 10 sats per kb and enter it at 00:00:00 forum time.

Can you post your TXID here?
