Complaint sub-issue: Didn't receive notice of right to dispute

Was trying to refinance my home was told I had an account in collections on my credit report. First I heard and looked didn't recognize the collection company I Q Data or the company they were working for XXXX XXXX. This was XX/XX/XXXX. I then called the collections agency to find out about this supposed debt of {$7600.00} that I had no idea of what it was and tried to explain to the man that this was not my debt and I had never received any documentation about this. The man started yelling at me and verbally threatening me I hung up and on XXXX XXXX XXXX received a letter in my name stating unless I wrote and disputed the interest would keep adding up. By this time the original amount had increased to {$7700.00}. I sent a registered letter to the collections company letting them know this was not my debt!. I had found the number of the XXXX  and their parent company XXXX  back in XX/XX/XXXX when I found out about this debt I called XXXX, XXXX to the XXXX   and XXXX, I was hung up.on told they would put in another request to tenant relations to find out why I had this in my credit. It turns out when my daughter and son in law didn't want to renew their lease because the new company was raising the rent way too much and no upgrades had been done on their unit, they gave their notice. They were 2 weeks late in moving out. Ok at least I think I know where they got my info. I have written to both XXXX and the XXXX   many times to show that this is my debt. Nothing received from either but I was told I should have signed a roommate re! ease. I explained I had never lived in their complex. To this date they have not sent anything to show this is my debt which it is not. I have disputed with the credit agency 's XXXX, XXXX  and XXXX the the address was one I lived at and it was removed. I have tried and tried to get something anything to show this debt is mine which it is not. But I am getting nowhere.not it is affecting my credit while trying to refinance the home I have lived in since XXXX. It turns out they say I was on my daughter and soninlaws lease the second year they lived thereXXXX to XXXX. I was not on that lease. After their first year lease XXXX to XXXX they signed a new lease on their own. I went into the complex office and requested not to do the second year lease since there was no Problem during that year, and they both were working and the office agreed and there was a new lease signed. It should have been done but there was no indication that this would still be a problem. They have never sent any paperwork showing this is my debt which I know they don't have. I believe the amount they are trying to collect from my daughter is wrong also and I have been trying to get this corrected also. After giving their notice that they would not renew the lease due to rent being raised way too much, they were harassed and harranged until they moved in XX/XX/XXXX. They also got no notice about this debt. I believe this company is trying to get my daughter for upgrades that were never done in my daughter 's unit. I believe they owe 2 weeks extra rent but since I have received nothing else from this company or the actual comp! ex I can not say. What I can say again this is not my debt!!!! The collection company finally sent and I received on XXXX XXXX XXXX a paper they say shows it is my debt ... the original lease from XXXX. Where is the lease that my daughter and her husband signed in XXXX. And btw I never signed anything electronically I signed in person by hand. There was no Problem from XXXX to XXXX. Nor from the beginning of the new lease which I was not on until they decided to not renew in XXXX. I did get to! d at some point that I should have signed a roommate release which I never was a roomate. Their numbers don't add up nor do the dates on the document. Whatever charges my daughter and her husband owe came after they moved out and to date have not been explained what it is for.
