For more than XXXX years i have a line of credit on my rental on XXXX XXXX XXXX XXXX my regular payment until last month was {$180.00}. I just received a statement from BOA for the current payment of {$580.00}, that is XXXX times more from last month. I called BOA and after XXXX mn wait, the lady on the phone advised me that she can not answer my question because i gave the wrong zip code, i have tax record on the property that shows the right zip code i gave her and i have a payment receipt from last month.
