I am dealing with Navient for XXXX private student loans. My sister paid {$11000.00} towards my loans to have her name remove as a cosigner. These loans went through XXXX collections agency and XXXX of them had no knowledge about the {$11000.00} payment. I started checking my account online and notice that navient did n't post the {$11000.00} to my account. I called them numerous of time and printed out documents from the online account. Then one day I decided to go on my online account and there goes the {$11000.00} payment but the balance remanded the same. First they told me that the online account does n't update because my account is with an collection agency and the information was n't correct. I asked them to send me information on my account and they only sent me information of my payment with the same balance as the online account. My thing is if the online account does n't update then why is the statement the same as the online account and why is my recent payment updated on there. I tried to get more documents on my loans and they refuse to send it me stating they was n't able to send me any documents. They keep sending me the same statement every time when I ask for something more detail. I try to contact the attorney that the judgements are with, but I get no answers and they never return my calls. They also had no knowledge of the {$11000.00}. I been going through this for three months trying to find the right balance because I calculated everything possible way to come up with the correct balance and it not coming close to anything they have and they refuse to send me documents and is giving a the run around.
