[Juliet Salceda]

I opened up an unsecured line of credit in July and wanted to request an increase. I want to know are there certains that I should do or have in place before requesting the increase. I knowt that the amount of the what was approved I should have only used about 30% of however if I pay the amount owed to the 30% max does it show when they check or do they go off of previous balance
