Product: Debt collection

To whom it may concern, My name is XXXX XXXX and I am disputing the accuracy of the debt on my credit report, reporting agency IQ Data Solutions in the amount XXXX of XX/XX/XXXX for an apartment complex debt with original creditor ( XXXX at XXXX ) The original lease was signed with XXXX at XXXX sometime in early XXXX, with my ex, XXXX XXXX XXXX. With about 3 months left on the lease, my mother became ill and I had to go to another State to help with her care. I made the apartment complex aware, and they said we could leave, but there would be XXXX dollar penalty for breaking the lease, and then we would be charged one months rent ( XXXX ) until the apartment was rented. I know 100 % for sure that the apartment was rented 2 weeks after we vacated the premises. I went to the new tenants ( our old apartment ) and asked them to RTS ( return to sender ) any mail that was sent to our old address for myself and XXXX. 
I contacted XXXX at XXXX numerous times 2 months after vacating the premises months to try and receive a finalized bill so I could make payments. After being told that the bill was on its way to my new address, I was then finally told that my account had already been transferred to a collection agency, and that they had my records in storage and could not tell me any more information. My last call with the apartment complex was in late XXXX when they told me to stop contacting them, and that I could only talk to the collection agency moving forward. 
In early XXXX I tried to get a finalized bill showing the charges from IQ Data solutions and numerous agents, in my opinion, broke several laws. Please see the following : 1. I was threatened with wage garnishment and tax garnishment 2. 3 agents used foul, derogatory language with me after I questioned their tactics 3. I was refused an itemized bill reflecting why I owed such a large amount 4. 2 agents threatened to sue me and take me for whatever I have left 5. ID Data Solutions called my father, XXXX XXXX and made him aware of the amount I owed and told him your daughter is running from a very serious thing and if you dont tell us where she works, you will be in trouble. 
In XXXX, IQ Data solutions went to court ( without me being served proper documentation or without me knowing ) and received a judgement plus 18 % interest. I was never served, or aware that I was being sued by IQ Data Solutions. They never made any reasonable effort to contact me and let me know about the ongoing litigation, except for the threats they made every time we spoke. 
I am not denying that I owe XXXX at XXXX monies, but after six years, I have never received any final bill, any documentation, and any itemized charge receipt to reflect why I owe such an absorbent amount. 
IQ Data Solutions has refused to talk to me, send me any documentation, or settle this debt in its entirety since they bought my account in XXXX. Also, IQ Data solutions broke the Fair Credit Collection act on several occasions.

The amounts currently reflecting on my credit report, and what reflects as my owed amount on IQ Datas actual website have almost a XXXX difference, which better proves that IQ Data Solutions is not aware of how much I really owe, and are adding on whatever amounts they feel. I have attached documentation to prove this. Because of the amount of the debt IQ Data solutions is claiming I owe, I have not been able to secure housing of any kind of my daughter and I, which is why it is important that I validate this debt, and pay the amount I owe, not an amount IQ Data Solutions has made up. 
I ask that IQ Data Solutions be held accountable, and this debt be deleted, as there have been many laws broken in them trying to collect random amount. 

Kind Regards, XXXX XXXX
