Product: Debt collection

I first got contacted the beginning of XXXX ( XX/XX/18 ) from a man, I advised that i can only be contacted after 5 due to work. The same man who was very nice and helpful, continued to call before 5 and after 5, finally we were able to set up payment arrangements on XX/XX/18 when he called after 5, he told me that they were getting ready to start the process to take me to court. On XX/XX/XXXX he called me back, same person totally different personality. He advised that I have 2 accounts and I have to pay immediately I explained my situation advised that I get paid bi weekly and since I already have 1 arrangement from 1 check I need to do it on the other check, he talked with his supervisor told me that he was not able to get any future arrangements approved so he sent me to his supervisor to talk and he still would not approve anything apologized and that was it, that was on XX/XX/18. A few days later I am still receiving calls all throughout the day, they left voicemails to my mother, step mother, step grandfather and high school friend ( that's all I actually know of could have been more ) advising that they need to reach me about a matter that I have and I am being taken to court. I have 1 copy of that voicemail. Very upset I called them spoke with the same man who wouldn't even let me get a word in, was yelling at me and demanding payment. I said I need your supervisor after fighting with me about it for a few minutes he hung up. I called again and was finally sent to the supervisor I asked if they record calls he would not confirm or deny, I asked if he keeps notes I said yes, I asked if he remembered the conversation of him telling me they could not work with me on XX/XX/18 and he said yes. I again requested that I do not get called before XXXX, and now that they do not call anybody or any other number but my own XXXX, and that I no longer want to be contacted by that man. He called me the next day, at XXXX. At that point I'm upset they told me they could not set up anything with me even though they could on my other account, and they are still contacting me. I then sent a written signed fax to them with my request that I do not get calls before XXXX, they do not call any number but my own, that the man who was calling to be taken off my account. A new supervisor calls on XX/XX/18 said they were confused by my fax that I sent XX/XX/18, I explained what it means he said okay no problem. He tried to set up arrangements with me however he could not get any account detail correct and kept apologizing that he was giving wrong information such as amount owed, and account numbers on both accounts so I declined setting anything up and requested that he sends me original documents from the original lender proving that I owe this debt. Instead he sent me a letter on their letter head that I owe a balance which I will include which I received XX/XX/18. They also called my mother again on XX/XX/18 and left a voicemail after providing them with 4 request not to call anybody but my personal cell phone number, XXXX of which were to an associate, a supervisor and a manager. And 1 was a written fax. I want to settle my debt, however as a single mother making {$12.00} at XXXX XXXX I am not able to pay what they are demanding when they are demanding it. I have not dodged calls to avoid them, only because when they mostly call its during Monday through Friday before XXXX.
