You're in Colombia? I find it pretty hard to believe any latino in Latin America would be so careless with their finances that they let $5 deposit fees hit them more than once per month.
But what do I know ... I'm just an Australian who's been living in Central America in countries much poorer than Colombia... but at least the people a little north of you are nicer. : )
That is poverty. $5 bank fees is not. Get a new bank or make fewer deposits.
