Key points
It is your right to request a copy of the documents you signed with the bank.
Request the copy at the time of signing or afterward and keep it, especially the loan agreement, card application, account opening agreement, and any attachments or declarations.
Having a copy is very important in case of a later dispute over fees, interest rates, or repayment terms, because you can compare what was actually done with what you agreed to.
The figures, fees and limits in this answer vary by bank and change over time — confirm them with your bank or the official source before acting.
