There is some business rules enforced in the my accounts page after your rent payment account is setup correctly.
The First name and Last name is "read only".
Since the ability to receive rent payments is based on your complete name accurately matching your drivers license, any mis-match can throw errors.
During the bank account setup process we validated this exact match. Therefore we can't let you change that, as this will cause error conditions.
We do not save bank data in our system.
You will soon see in our society that name match matters.
For example (2017): Latter this year your name on the airplane ticket must match your drivers license and or passport or you can't board the plane. As these new rules are spread across our society -- we too must comply.
