Complaint sub-issue: Didn't receive enough information to verify debt

Hello, Here is my concern ; I had a lease agreement with XXXX XXXXXXXX XXXX XXXX from XX/XX/XXXX to XX/XX/XXXX. We moved out at the end of our lease agreement, giving a proper 60 day notice to management, and fulfilling all of our financial obligations. We never heard again from XXXX XXXXXXXX XXXX 
In XX/XX/XXXX I became aware that XXXX XXXXXXXX XXXX XXXX  had open a collection debt account in XX/XX/XXXX for the amount of {$560.00}. That is 7 months later from our lease agreement coming to an end. In that time frame they never attempted to notify and let us know there was a pending balance in our account. Nor sent us a balance statement showing the amount due. Nor gave us the opportunity to dispute such balance. In XXXX, XXXX, PROCOLLECT , INC, took over the debt in the amount of {$560.00}. I finally became aware of this debt because I checked my credit report in XXXX XXXX. In XX/XX/XXXX I went to talk to XXXXXXXX XXXX XXXX  to request an itemized statement that could give me more information about the {$560.00} balance. However, the new management mentioned they had just bought the XXXXXXXX XXXX XXXX from XXXX XXXX XXXX therefore, they had no records from previous tenants. They recommended for me to contact XXXX XXXX or PROCOLLECT , INC to request the information to verify the debt. 
In XXXX XXXX I submitted my first request to XXXX XXXX through their customer service email XXXX and XXXX, to receive additional information in regards to the {$560.00} balance, requesting an itemized statement to verify debt. - NO RESPONSE FROM THEM. 
Also in XX/XX/XXXX I submitted my first request to PROCOLLECT , INC through their Consumer Inquiries Online Portal, to receive additional information in regards to the {$560.00} balance, requesting an itemized statement to verify debt. - NO RESPONSE FROM THEM. 
XX/XX/XXXX, since I didnt hear back from XXXX XXXX  nor XXXX XXXX, I submitted my first dispute through XXXX XXXX XXXX 45 days later the dispute results showed the collection account had been " UPDATED '' by PROCOLLECT INC, with no additional information provided. Since XXXXXXXX XXXX could not tell me any information in regards to the itemized balance statement I had requested, I submitted a dispute through XXXX on XX/XX/XXXX. By XX/XX/XXXX Experian Results showed that XXXX XXXX, certified XXXX that the information about the {$560.00} is accurate. Therefore item was not changed or removed from my credit report. So since XXXX certified the information but I still did not have an itemized balance statement, I attempted, for a second time, to contact PROCOLLECT INC to get an itemized balance statement that could show me detail charges of the {$560.00} owed to XXXX XXXXXXXX XXXX I submitted a second letter to them on XXXX XXXX through their customer service email XXXX. Again I asked for their assistance to supply an itemized balance statement and additional information on the account. I provided my PROCOLLECT Account Information, in addition to my mail address, email address, and phone number hoping someone would get in touch and provide the information I was requesting. - as of today XX/XX/XXXX I have not received a response from PROCOLLECT. 
In XX/XX/XXXX I also sent a second letter to XXXX XXXX asking for their assistance to supply an itemized balance statement and additional information on the account. I provided all the information I knew about the account and lease agreement, in addition to my personal contact information, mail address, email address, and phone number. As of today XX/XX/XXXX I have not heard from XXXX XXXX 
I've provided XXXX with all the requests letters I have sent to XXXX XXXX, PROCOLLECT INC, and XXXXXXXX XXXX XXXX  XXXX XXXX, trying to show I'm trying to make contact with PROCOLLECT INC and get the information I feel is within my rights to request from them, as simple as an itemized balanced statement showing the detailed charges of why XXXX XXXXXXXX XXXX processed a debt against my account 7 months later after we moved out, and no attempt to notify us about this balance. I find very interesting and frustrating that PROCOLLECT INC does respond to XXXX request but they are not responding to my requests. 
I find extremely out of the ordinary that a Collections company, usually known for calling you non-stop and sending you letters to collect payment etc. has not attempted to contact me once. I have provided them with my mail address, phone number, email address through different public communication channels and I have not received not even a notice to collect debt. 
All I'm asking from the Consumer Financial Protection Bureau ( CFPB ) is to look into this request, that is within my rights, to request an itemized balanced statement to verify the debt posted on my credit report. If either PROCOLLECT INC or XXXXXXXX XXXX XXXX can provide this item and it turns out that I legitimately owe this amount, I will be happy to take care of it and pay it in full. All I want is proof and justice. I sincerely hope the CFPB is able to help. At this point I'm not sure what else to do to take care of this issue. 

Here is the contact information I have about each company.
