I XXXX XXXX reached out to Aldridge Pite Haan on XX/XX/XXXX @ XXXX requesting information about a certified package I sent and has been received by their office on XX/XX/XXXX. My phone call was answered by XXXX XXXX whom after pulling up the case information advised me that he would need to transfer me to his supervisor XXXX XXXX. Before XXXX XXXX was able to transfer me I asked him what was the protocol for returning calls at his company as I have left many voice mail messages for XXXX XXXX ext XXXX on XX/XX/XXXX and have yet to receive a return phone call. XXXX XXXX advised me that he couldnt assist me nor could he tell me the timeframe before I would receive a call back from Mrs. XXXX and he would transfer me to ext XXXX as she is the only one able to assist me with this file. He would also send Mrs. XXXX an email. I was transferred and I left a voice mail message requesting a call back once again from XXXX XXXX. I also sent a complaint email to Aldridge Pite Haan online complaint. I have attached that email. 
I received a phone call back from XXXX XXXX @ XXXX, but that phone call ended briefly as she expressed she was having computer issues and requested that I give her time to re-boot her computer and call me back. 
Again I received a call from XXXX XXXX @ XXXX. Mrs. XXXX went on to tell me that the judgement would stand as they had gotten information from XXXX County Court showing I was served on XX/XX/XXXX. I responded to this correspondence in XX/XX/XXXX and have addressed this in my previous complaints. Mrs. XXXX stated the current balance on the file as {$1800.00}. I asked Mrs. XXXX about the police report and victims identity theft complaint and affidavit that were received at her office on XX/XX/XXXX. I wanted to know if an investigation would take place now that I had the report. Back on XX/XX/XXXX Mrs. XXXX explained to me that I didnt have a police report and therefore no investigation would take place, but if I was able to send in a police report an investigation would take place. I previously included that information in my last complaint. I was then informed by Mrs. XXXX that the received documents would not be investigated, but added to my file and we could settle. The case would be dismissed as long as I relinquished {$810.00} that is currently being held in the court registry. After going back and forth Mrs. XXXX advised me that she could get a dismissal letter from the firms lawyer sent to me via email within a few days. I gave my email address and I also gave Mrs. XXXX the XXXX County Hospital HR employee XXXX XXXX email to receive a copy of the dismissal as well. I informed Mrs. XXXX that I am reluctant to take the settlement as I do not owe this debt. 
I am so confused as I dont understand why an investigation wouldnt take place now that I have a police report? How is it that Mrs. XXXX is willing to settle for {$810.00} and dismiss the case now, but before the settlement offer was {$1400.00} ( a  one-time payment ). I am requesting a full investigation into this matter and all garnished funds returned to me as I have submitted the police report along with the victims identity theft complaint and affidavit as instructed. This case is and has always been a FRAUD case and I have presented all of the documentation that I was instructed to send in. 
I even contacted the XXXX County Court and XXXX County Hospital to verify the amount currently being held in the court registry and at this time it is {$750.00}. The same amount showing collected on my earnings statement. I am confused as to how Mrs. XXXX came up with the amount of {$810.00}. I was advised on XX/XX/XXXX that if I could get a police report an investigation would take place and now I am being told that is not going to happen. I do not owe this money and would like to know why an investigation is not taking place? Why the full amount is not being refunded to me? All of this information can be verified as I am always instructed during our calls that they are being recorded.
