Bitcoin Core

Bitcoin Core makes making Full RBF transactions very easy. Simply go to the transactions list, right click the transaction that is stuck, and choose the "Abandon Transaction" option.

If that option is greyed out, then you must restart Bitcoin Core with the -walletbroadcast=0 option and then you should be able to use "Abandon Transaction".

If the above two options fail for some reason, then you can start Bitcoin Core with the -zapwallettxes option to clear all unconfirmed transactions from your wallet.

Once the transaction is either Abandoned or cleared from the wallet, you can simply go to the Send tab and send the Bitcoin again but make sure that you include a sufficient transaction fee.

I have tried https://www.viabtc.com/tools/txaccelerator/ numerous times but I keep getting this error "elerator Submissions are beyond limit. Please try later."

It's because there's a limit in number of transactions that they accept (try it in an hour and hope for the best). Also due to the huge backlog (at the moment) majority try to use ViaBTC as well (so getting it to successfully submit is a bit hard)
