Capital One Credit Services used a law firm, who placed a judgment on me in 2008. I went to court and agreed to pay $50 a month for charges that occurred in 1994. I paid $1500 before I missed 3 consecutive payments. I sent a check for the 3 months, $150, within that third month. Capital One didn't cash that check, instead they placed a freeze on my bank account in which they took $400 from my account. The law office is now trying to contact me, why?
