there are a few things about bitcoin you should know it, bitcoin payments are irreversible this mean transaction cannot be refunded, it can only be refunded by the person receiving the funds.
Wow, thanks for telling us. Nobody knew about that and this is not the reason why OP is asking whether reversible transactions can be added.
one of the shortcomings of bitcoin or it can be said of a bitcoin wallet about a transaction that is not refundable if we transact on an unknown person, except when the person who we can know the solution is sent back to our wallet.
It's not a shortcoming, it's a well thought option that makes it similar to transacting in cash. If you meet someone in the street and that person sells you something, you accept the terms, pay and walk away, you can't get the money back. It's a normal thing that puts both parties on the same level. If you used the item, broke it, and demanded a chargeback it wouldn't be fair towards the seller, would it?
