GMAC froze the $100K line of credit in early 2008 with only a $2500 balance. Initially, they sent me the letter of notification of the freeze. On my next statement, they charged me an annual 'use fee' even though the line was frozen. After many conversations I got the fee waived as an obvious excessive charge. Now, while I have not had use of the line and having lost six figures on the sale of my home, I am paying it off and they are charging a prepay penalty of $500 for this paltry $2500 balance and won't waive it. Seems ridiculous and excessive. Any others have similar issues? read full review »
