In approximately XX/XX/XXXX, I consolidated my Stafford Loans with Fedloan. I have been paying my loan repayments on auto pay with my bank account ever since. I never missed or was late on one payment. I set up my auto pay to pay {$110.00} per two weeks to the sum of the minimum due ( {$220.00} ) per  month. I never received any notification of any changes to my account. In XXXX of XXXX, I reviewed my payment history and the amounts of money being disbursed by Fedloan to the Principal and Interest. To my disbelief, I noted that several months the full payment went to interest only and {$0.00} to principal. I called Fedloan to inquire as to why my principal was not going down even after paying ahead on some months and never less than the minimum required. I was told my minimum payment went up ( $ XXXX ) which I was never made aware of, nor believe is possible or legal. I added to my auto pay to make my biweekly payments {$150.00} per two weeks a total of {$300.00} per month or greater where twice a year there are moths with 5 weeks and 3 pay days. I even sent in an extra {$300.00} in XXXX of XXXX to make sure I was ahead on payments. 

On XX/XX/XXXX, I called Fedloan again as I found more transactions where {$0.00} of my payments were applied to my principal. I spoke to over 4 different people who treated me very poorly and as though I was ignorant and bothering them. Finally, I spoke to XXXX ( XXXX ). XXXX reviewed my transactions with me while I was on the phone. I used the XXXX spreadsheet to give XXXX the exact dates of my {$0.00} applied to principal. Finally, XXXX understood my concern and told me, this will go to Service Recovery Department and It is notated in the review status my concerns. I was told by XXXX that I would be contacted within a week. Here it is nearly 1 month later, and I still have no answer as to why I make the full payment and even more than the minimum payment and yet {$0.00} goes to interest. 

I will attach the spread sheet which I downloaded directly from Fedloan. Additionally, here are the dates of my questioning : ( XX/XX/XXXX XX/XX/XXXX ), ( XX/XX/XXXX XX/XX/XXXX ), ( XX/XX/XXXX XX/XX/XXXX ), ( XX/XX/XXXX XX/XX/XXXX ), ( XX/XX/XXXX ). It should also be noted that many months greater than 90 % of my payment went to interest while the remaining 10 % went to principal. There were almost 60 months were less than {$12.00} went to principal per payment made. 

Again, my question which still has not been answered is as follows : how can I make the minimum or greater payments per month, be ahead on payments, and still have several months worth of payment which {$0.00} was applied to principal? I would be grateful if this can be answered and investigated.
