On or about XXXX/XXXX/XXXX I received an automated auto robot call from NAVIENT telling me that I still had student loans balance that is in default. I thought it was a scam, so I hung up and contacted NAVIENT directly. They confirmed to me that my student loans were paid in full on XXXX XXXX, XXXX. I have documentation to support this claim. A NAVIENT customer rep stated that there seems to be a problem with loan # XXXX ( ending with XXXX ) that this loan was not consolidated. According to the rep this loan belongs to XXXX XXXX XXXX XXXX, which I have never heard before nor taken any loans from this servicer. I explained this fact to the customer service rep at Navient. It is my understanding that in XXXX XXXX XXXX XXXX XXXX were transferred to NAVIENT. This is important b/c after doing some research XXXX XXXX XXXX XXXX appears to be as previous XXXX XXXX lender. According to my records the account loan number XXXX was consolidated on XXXX/XXXX/XXXX to XXXX XXXX, who later transferred to NAVIENT. I complaint how come I had not received an account statement in 3-years to my NAVIENT customer service rep. The customer service rep could not provide me with an answer and instead provided me the following telephone number to contact for more information XXXX XXXX XXXX XXXX. All of my student 's loans were consolidated and PAID -IN-FULL. I do not understand how come I keep getting these calls and they can not help me with this issue. I continously get harassed with these robot calls. I know that there was a security breach with NAVIENT, I do not know if this are scammers and they are very good at it. I have contacted the ( XXXX ) XXXX telephone number provided by the NAVIENT customer service rep, when I enter my social security number or account number as stated above, they state that there are NO EXISTING account with this information. Furthermore, I logged into XXXX XXXX XXXX XXXX and their website stated that I do not have an account with them, that there are no existing accounts ( I have supporting documentation of this as well ). I do not know who dropped the ball, but if there is any balance remaining out there for any student loan, I have not been provided with an account statement for over 3-years. I believe NAVIENT failed to paid those debts to other consolidated servicer loans such as XXXX XXXX. It is my understanding that NAVIENT took over XXXX XXXX XXXX XXXX back in XXXX. All of my student loans were consolidated into NAVIENT and all balance paid in full in XXXX/XXXX/XXXX. Please help me resolve this issue. I am very XXXX  about this because I continue to receive robot calls saying that I owe money and that I am in default. I do not owe any student loan debt and I do not know where they are coming with this information. I have been going in circles about this issue. The NAVIENT customer service rep is unable to provide me any specific answers. They simply say that all of my student loans were paid in full but that I still have a balance with loan # ending XXXX. Again, she could not tell me how much was the balance and provided me a telephone number that I could call, which was the ( XXXX XXXX XXXX which according to them belongs to XXXX XXXX XXXX XXXX. If you need further information please contact me. I need this issue resolved as soon as possible and stop receiving these automated calls. All of my student loan servicing lenders have my physical address and my contact information. Account statements should have been mailed to my home address if there was still remaining a balance. I have not received an account statement for over 3-years. Until recently, I begin to receive these harassing robot calls.
