Aqua Finance MBC investments Charging for debts that were put into bankruptcy Wausau Wisconsin

 In 2008, my ex-wife and I purchased a water purification system, and financed it through Aqua Finance. After our divorce in 2011, we established that this debt and a few others belonged to her. She ended up filing for bankruptcy. When she asked about the water purification system and how it would effect both of our credit, she was told that they would reclaim the system, and that it would show as a charge off. Not long after the bunkruptcy was finalized, I started receiving phone calls from Aqua Finance, asking me how and when I intented to pay the debt. I informed the gentleman that I was speaking to, that the debt was charged off through bankruptcy, and that they were supposed to retrieve the system. He then told me that they didn't want or have to retrieve the system and that I had to pay for it. He also stated that it would reflet on my credit report. I pulled a copy of my credit report, and in showed a joint debt that was owed to Aqua finance had been charged off, and it showed a new debt opened under MBC investments as an individual account. They have also added a little over $3,000 in fees. My credit score took a major hit, making it impossible for me to get even a small loan, even with my high income. I am currently disputing this with the credit bureus.
