Product: Student loan

I graduated college back in XXXX. Ever since I've had many back and forth interactions with one of my student loan servicers, Navient. 
I graduated during the aftermath of the Great Recession so good paying jobs were very hard to come by so I had to take a job that paid $ XXXXhr. As you'd expect, I was having serious issues paying my $ 70k+ in student debt. I had tried countless times to work with Sallie Mae/Navient to get myself into an affordable payment. They would let me catch up when I fell behind by telling me to go into forbearance. They sold it to me as a " don't worry, we know you are having difficulty paying. You can be brought up to current if you forbear your loans. To do so, you have to pay $ 150- {$400.00} ''. I did this more than one time. 

Now 85 % of my student debt is in Private Loans that according to Navient originally totaled {$49000.00}. I have been out of school 8+ years and have been making payments set up by Navient where they set the amount and then automatically withdraw money from my account. I made the mistake of trusting that they had my interests in mind when they set up the payments. So a couple months ago, I went to refinance my home and was denied because of negative amortization on my Navient student loans. I said to the loan officer "  What are you talking about. I've been on a repayment plan with them for years! ". They said well it looks like the payment plan you are on is not covering your interest so your principle has gone up. I originally borrowed like I said, {$49000.00} in private student loans. My current unpaid balance is {$66000.00} and have been making payments for 8 years ( with some intermittent hardship along the way, but I have been sending them money ). 
Upon learning this, I reached out to Navient and asked them why have I been making payments, that they set up, and my balance has been going up. They said we'll look into this for you. And you should hear back from us in 12 business days. 20 business days went by and I called them back up. " Do you have any updates? No. It doesn't look like they've gotten to your request. I'm on the phone with you now, let me check out what I can see. '' And after a very long call the representative said that well your balance is going up because the payments are not enough to even cover the interest and it looks like you have 4 loans that are on " Administrative Forbearance ''. I told her that I did not request this forbearance at all and asked if she could get someone to figure this out. One thing to note, these student loans were my 4 highest interest rate loans : One at 9 % and three at 6.75 % totaling {$32000.00}. Needless to say I followed up a couple more time and finally I got someone to help me and tell me the result of the investigation. All I got was " We don't know why it was put into Administrative Forbearance ''. All they said they could do was take them out of that un-requested forbearance. I asked them to send that information to me via mail because I wanted to get it in writing. They did but it admitted no fault and that those loans are not long in forbearance. I feel cheated and really feel that I've been taken advantage of. I have loans that I took out in XXXX that if I now pay the bare minimum, wont be paid off until XXXX. That's 35 YEARS. I feel like I'm in a sinking ship and it feels horrible. I will attach what I'm looking at
