Product: Student loan

I have private loans with Sallie Mae that my sister was nice enough to co-sign for so I could go back to school. After graduation I contacted them about removing my sister as my co-signer. I was n't aware that they had certain criteria that needed to be met before doing this. I went through the motions and made sure everything they required I had completed. I applied for the co-signer release in XXXX XXXX. They denied the release stating that I did n't make the XXXX consecutive monthly payments. After researching my statements I saw that in XXXX XXXX I made the payment on the due date, but since it did n't post until the following date they claim it was late. So I continued to make my monthly payments and well before the due date until XXXX XXXX. After making the XXXX XXXX payment, I again applied for the co-signer release. Again, I was denied. This time they state my credit score does not meet their XXXX requirements. The score listed on the letter I received from Sallie Mae is about XXXX points less than what other sites are reporting my score at. Sallie Mae 's letter says the date they pulled my credit was XXXX/XXXX/XXXX and the other sites I use to monitor my credit say the information was updated XXXX/XXXX/XXXX. After calling their customer service and speaking with them, they told me it 's not my score that affected the decision, it 's the fact that I do n't make enough money to handle the repayment of my loans on my own. I have been paying the loans by myself since I graduated. My co-signer has never had to dish out even one penny to assist in my repayment. In addition to this, my boss has been kind enough to assist me in repaying my student loans as part of a tuition reimbursement program. I have a letter, on business letterhead, stating that they are going to be making the payments on my behalf the rest of the term of the loan. They are basically going to write me a check every month for the total of my monthly payment, I will deposit into my account, and make the payments like I have been doing. This situation is also affecting my sister ( co-signer ). She has been looking at houses for over year. Until she has her name removed from my loans, she ca n't proceed with purchasing a home as she has her own student loans in here name and the bank wo n't finance her with the total loan debt of both her personal loans and mine that she co-signed for. In XXXX when the co-signer release was denied she put off house hunting until I became compliant in XXXX XXXX. She 's in a position now where she HAS to find her own place but ca n't move forward until she is released as the co-signed. I do n't understand, I have made the payments on time with no assistance from anyone else, I made a decent salary, and now I have a financial guarantee with my boss essentially making the payments for me. I know my credit score is n't the best, I did go through a debt consolidation a few years ago which drastically lowered my score, but I am less than a year from completing that. All but XXXX account has been paid off through the program. My only opens loans are student loans and auto loans. I have XXXX judgement from a creditor that I had enrolled in the program, but that judgement was satisfied. And I have XXXX medical bills in collections that I am currently working on getting paid off.
