Product: Student loan

I have had MANY problems with Navient since XXXX, when I first started making payments. I have 8 Private Loans with them all with co-signers. I am also part of the XXXX settlement, post-class. Below are my on-going and continuous problems with Navient : Problem 1 : I am paid every other week, so Navient splits my monthly payment in 2 and withdraws from my checking account half the full amount each time I get paid. For months I get paid three times that month, I always tell them not to withdraw my checking account for the 3rd pay period. Sometimes they withdraw from my checking account that 3rd pay period and sometimes they do not. Either way they do it, I get bumped out of my payment programs and have to spend an additional 1+ hour to get this resolved. The last time this happened was XX/XX/XXXX and it took me 2 months to get this resolved. They did reimburse me the extra payment I made only to set up additional monthly withdrawals of {$1700.00} every month on top of the {$1600.00} I already pay them monthly. I had to call a 3rd time to get the {$1700.00} reimbursed and that additional monthly withdrawal removed from my Navient account. Every year I deal with this multiple times and am told completely different reasons as to why this happens with no accountability on their part and them telling me I did something wrong. 
Problem 2 : Misinformation amongst Navient employees is rampant! I ask them to record EVERY time I call so there is a trail of what was said. I know they do not listen to the recordings, but theres nothing I can do about that. I have been told many times two different things by two different people and both were wrong which usually only hurts me. I am also told that I misunderstood what was told even though I write everything down. I ask them to review the recording of the conversation and they tell me they do not need to and all they need to do is read the notes from the previous CSR which are also usually wrong or only have half the information. Every time I point that out, Im told there is nothing they can do. 
Problem XXXX : Ridiculous interest rates! I have paid over {$230000.00} since XXXX on loans that originally totaled {$220000.00}. I currently still owe {$240000.00}. I will never get these loans paid off and that is ridiculous. 
Problem XXXX : I have requested MANY times to have my cosigners released as I have met the criteria and they deny it every time with no explanation and when I call, no one seems to know why even managers. 
Problem XXXX : Their late fees are out of control. I have my payments automatically withdrawn from my checking account where I have NO control over the amount taken out and yet, I am constantly being charged late fees. Most of the time that happens after Problem 1 occurs and when I bring it to their attention that it was not my fault, they still charge me noting, there is nothing I can do about that. If youre late, we have to charge you, totally disregarding the error was not on me. Again, XXXX accountability on their part with all the blame on me for something I have no control over. 
Navient is a horrible lender with unscrupulous business practices. They prey on students, especially those from scam schools which mine was XXXX, XXXX, and it is next to impossible to repay them back in full. They have called friends and family of mine that I never gave them their information nor permission to call. They are never at fault, always assume I am an XXXX, and never provide me the same information twice even when I call with the same problem. I just can not tell you enough how much they have made my life and my cosigners lives difficult. My credit score has greatly suffered as has my cosigners for problems I did not create. They have yet to repair our credit scores as they promised they would and I just want them out of our lives!
