Product: Student loan

I have both federal and private loans through Navient that I first began paying on in XX/XX/2014when I graduated with my XXXX. I ended up going back for my XXXX degree and not only deferred those loans but took out additional federal loans to pay for my XXXX degree. I graduated almost 2 yrs ago and began paying, what I thought was, my total sum of all my loans each month. It wasnt until 6 months had passed that I realized Navient was misallocating my payments but had no idea or lied to me about what was going on. Navient was using my entire payment for just my federal loans, while putting absolutely nothing towards my 3 private loans ( of course the ones that have a higher interest rate and are impossible to get help or assistance to begin with, which I only need now because of Navients negligence and deceitfulness. I would constantly get calls and notifications that I was past due and they were going to report me but every time I would check my account or call they would tell me I was current and I took their word for it because I had no reason not to. It did not seem phantom-able to me that what was occurring would occur to begin with but also continue to happen nearly a year and half after I first realized how irresponsible this company was. I have come to believe what they are doing is criminal because they have blatantly disregarded not only the common sense and ethics they should be working with but also purposely lying to me about where each payment went to. Even worse, my father co-signed two of these private loans so now they have not only began to ruin my credit and make it so difficult to get on track with my private loans, they have done the same to my father. By the time Navient figured out, or finally told me what they were neglecting to for 6 months, my past due payments were almost {$4000.00} for these 3 loans. I had basically two options pay they {$4000.00} or join a payment plan which ended up being {$500.00} twice that month and {$500.00} every month for the next two years, on top of all my other loans I had to pay for. Within 3 months I was unable to pay the over {$1000.00} total payment they were expecting of me. I tried to work with them to figure out my situation with 0 help from them. I ended up consolidating and taking a forbearance on my federal loans so I could afford to catch up on my private ones, that, mind you, wouldnt have been past due or high, if one person at this company did even just one task a day that we would all expect them to do. While this arrangement was manageable since it began and I thought maybe Navient was getting their act together, they have misallocated 2 payments of {$500.00} in the past two weeks. They are back to stealing customers money and freely distributing it to wherever they feel like, while ruining their customers credit and ability to manage student loan repayment. I will be giving them another {$500.00} for the same loans I gave them {$1000.00} the past two weeks for or my father and I will be reported. This is after I called them when they messed up the first time and they reassured me it wouldnt happen again. With a company like this, no wonder people cant afford to pay the their loans back, its criminal and disgusting. Although I take some responsibility for not knowing exactly what was going on or putting more pressure on them to get answers for what was going on at first, be very vigilant of Navient, because this is still happening when I have done everything correctly to stay current on all my loans. But by far the scariest part, is not only is it still happening, they have lied to me twice now about it. This company and its employees should be absolutely ashamed of themselves.
