Citibank review: Credit card judgment lien against my property unreleased for over 8 years

My husband and I are currently working with our local credit union to open HELOC. Their underwriters in doing the property search discovered an active lien on our property in the amount of $3531.23 filed on 2/11/15. In researching, I discovered it was in regards to a judgement that was filed against us 7/24/12 from Citibank for a credit card we had defaulted on. At that time Buffaloe and Associates were handling the account. We went to court and worked out a repayment of the debt and on 11/30/15 we paid off the debt thru the county court. In the midst of the court approved repayment on 7/24/15 we received a letter form Lloyd & Mcdaniel with a substitution of Counsel and on 2/11/2015 the judgement was filed with the county, almost 3 years after the approved repayment agreement and 9 months before we paid the account in full. We were never late with any of our payments, so I am not sure why they chose to file at the late date. Bringing the current, I reached out too Buffaloe and Loyd & Mcdaniel to discuss if the release of judgement had been sent and just somehow lost and not recorded with the county. Both companies advised me since it was closed with them that I would need to contact Citibank directly to obtain that information and /or release. One rep at Buffaloe provided some phone numbers, and this is where the main part of the complaint is created. 10/16 and 10/17 I have attempted to reach the department at Citi bank that will be able to release this judgement. Of the 5 customer service reps I have spoken to, I have been told that they cant transfer me to that department without the account information and cant or wont transfer me to their supervisor. They state they dont have access to that information. One rep gave me a number that turned out to be the citi Bank mortgage department which couldnt help because I never had a mortgage. Only a credit card. Today I was told because I was not the primary card holder that they could not provide me with a phone number at all, I advised I was an authorized signor and authorized to discuss the account when it was open, but they would not listen. Most didnt take the time to understand what I needed, most, in my opinion didnt even know what a lien was and why it was an issue. They were rude on top of ignorant. There is nothing online that gives me any direction of who to contact to help me. I have reached back out to LLoyd &Mcdaniel today to try to work this out thru them, but I dont think they were the final company that covered my account as I also have a letter I obtained in 2020 from Aldridge Pite Haan stating my acocunt was paid in full. I have left them two messages but no one has called me back from there. This paid in full judgement is on a paid off card from a case over 10 years ago with the judgement having been paid in full for over 8 years ago now. At this point we are unable to finalize our HELOC, and we are out of options of how to resolve this unless one of the attorneys takes the responsbility or Citibank finally puts us in touch with the correct department that can help, which we are beyond frustrated and wish to not deal with them anymore because of how we have been treated. I also would add that this is not showing on my credit report at all. I have supporting documents but couldnt upload them
