I am interested in the product, I have a few questions

Does it work in all parts of the world?
Is it tested in South America?
Directions, maps of cities in Argentina.
And above all, the telephone code (number of digits, varies according to the country and the state)

is it multilanguage? I need the possibility for users to see texts in Spanish. All texts, labels, messages, everything.

Type of payments, such as bank accounts.
In Argentina, CBU code is used to make bank transfers, cbu is the unique key of a bank account.

What kind of graphic parameterization can I do?
Change colors? logos? fonts?

Do you have support in Spanish at your staff? assistance in Spanish?
