I am paying them monthly, don't dispute the bill.  What I do have a problem with is that when I shed in my monthly payment, they take up to 10 days to post the payment.  I send it monthly via certified mail and request a letter stating amount of payment, balance and date was posted.  Very glad I send certified as las t month received a call wanting to know where payment was, able to provide usps certification number, date and time it was signed for, in addition was able to give them the money order number (never send a check with your personal info on it)  y providing that info was able to prove they had the payment but had not posted it.  As I told them, not ,y problem you do not post pay,nets in a timely manner.  Always send payments in certified mail, use a onye order and request letter showing.pY net amount, Alan e and date posted to account.
