Do you mean abandontransaction?
In that case, if you didn't see an error message, i wouldn't worry about it anymore.. You abandoned the transaction, that's all you needed to do

I'm glad to see you got it solved, however, there is one thing i wanted to clarify:
walletbroadcast  => Make the wallet broadcast transactions
zapwallettxes => Delete all wallet transactions and only recover those parts of the blockchain through -rescan on startup

There is a big difference between the two: the option you used just makes sure your wallet doesn't rebroadcast your transaction. The second option (zapwallettxes) makes sure the transaction is deleted from your wallet, so it'll never be rebroadcasted (since your wallet simply deleted the transaction).

If you only have 1 unconfirmed transaction, they're equal in security... The main differences are that abandontransaction is a command you can run from the cli or the debug window while your client is running and it only abandons the 1 unconfirmed transaction you enter as a parameters. -zapwallettxes is a startup parameter, it can only be issued when starting the client, and it usually takes a lot longer to do this compared to using abandontransaction. Zapwallettxes also removes ALL unconfirmed transactions you have broadcasted...
On the other hand, abandontransaction doesn't always work (you get an error message that the transaction cannot be abandoned). In this case, you'll have to use the zapwallettxes parameter (i'm to lazy to look up the spelling, but i think -zapwallettxes might be misspelled).

BTW: next time you have a problem, it might be better to start your own topic, replying to a 6 month old topic is usually considered necroposting, eventough you have a valid question (just a tip)

Which wallet are you using? For example, bitcoin core keeps rebroadcating a transaction untill you start it with -zapwallettxes or issue an abandontransaction from the cli
