App has several and dangerous issues.
One transfer was sent two times from my account due to a bug in the app (the confirmation of payment was two times in the screen), the solution they proposed was "send an email to the receptor to ask for the money back, if not we could make a payment study with an additional charge of 15€", pretty disappointing solving issues, also you cannot print extracts or transferences in other languages different from the default. In the case of transactions, they do not have any type of ID or way to differentiate them if one was done twice. The card is awful and weak, sometimes it does not work properly in stores. It is a bank, procedures and customer help should be a *priority*
