The transaction to the FITFI contract address.
Hate to be the bearer of upsetting news, but if you sent your funds to the contract address, we can't retrieve them as no one has access to the contract address, and it's technically not possible.
The transaction to a random/mistyped address.
There's a chance that the owner of the address will send it back, but there's no guarantee.
The transaction to the wrong address is pending. Can I cancel it?
Due to the fundamental trait of the blockchain, it is not technically possible to cancel transactions once they are sent.
