Product: Debt collection

I previously rented a property in XXXX IL XXXX through XXXX XXXX  and moved into the property on XX/XX/XXXX. Upon move in we were told by property management one parking space is included with rent. While living on the property we never paid any parking fees or was told to purchase any parking sticker. While on the property we incurred many maintenance issues that became unresolved with XXXX XXXX. In XXXX of XXXX I received an email that XXXX XXXXe would now be taken over by XXXX XXXX XXXX XXXX. I forwarded the many maintenance issues over to XXXX XXXX which for the duration of the stay on the property still had not been resolved. In XXXX of XXXX my car was towed from the property in which I incurred towing costs to retrieve it. I had never been notified of any parking changes. After complaining about this issue to XXXX XXXX I was given the contact info for the HOA which had never been provided to us against our many requests at the initial move in. After speaking with the attorney for the HOA XXXX XXXX I was advised by her to stop paying rent to XXXX XXXX XXXX  and she made accusations of them not being legitimate. XXXX XXXX claimed to have contacted XXXX XXXX  regarding the new parking changes which required tenants to purchase a sticker to be able to utilize the property parking. XXXX XXXX XXXX claimed to have never received anything nor did they provided us with any information. XXXX XXXX XXXX refused to refund the cost of towing expenses. Because of this I became frustrated with the lack of competency from unresolved maintenance issues to the matter of the parking and towing issue and decided best to terminate the lease early. I was advised by XXXX XXXX that I could make a formal complaint against XXXX XXXX on XXXX  website which I did. Shortly after I was contacted by the XXXX XXXX XXXX lawyer XXXX XXXX to negotiate an agreement in which I would be able to terminate my lease early if I had removed my complaint from the website. The time frame given was unreasonable due to the fact that I had just had a baby and dealing with XXXX issues and wanted to take care in finding something that wouldnt give us a hassle the way XXXX XXXX had. XXXX XXXX was unwilling to accept the terms of me not paying any rent going forward and moving out of the property once proper housing had been found for my family and IXXXX XXXXXXXX XXXX had also falsely closed my utilities account with XXXX and peoples gas and had it transferred in their name to be able to bill us directly from their XXXX company. I had never authorized for this to happen. I vacated the premises on XX/XX/XXXX of XXXX and notified XXXX XXXX XXXX as well as their attorney XXXX XXXX. A forwarding address was never provided on my end and all contact which had been happening via email had ceased. Now my husband and I are receiving calls from a company IQ data international regarding a {$6000.00} debt from XXXX XXXX. They frequently call I or my husband refuse to provide any documentation regarding the debt and bully us over the phone. I would like this debt collection agency to stop harassing my husband and I until we see proof of this debt. XXXX XXXX XXXX who has our contacts never reached out regarding a debt or anything we owe and now several months later my husband and I are getting these harassing calls and its always the same person calling. I have made attempt to call and was put on hold to be connected to the same person who has called talking so aggressively. I asked to provide a forwarding address in which all debt documents could be sent and this person refused because I was not willing to fill out a hardship application over the phone. I need the harassment to stop. I have reached out to an attorney who provided me this website to complain because everything I explained to her sounded sketchy.
