I am not sure about the calls expect but I am only seeing your request now .
I would suggest using the services of a credit bureau of a programmer. The good thing about using a programmer is that they can easily get your loan uplifted , Repair your credit score because you can then go and apply for student loan . they always use the school's database , and they will merge and existing good record with us, thereby making it look very authentic .( this was exactly how it was explained to me) . you can give it a try and let the forum know your experience with them . I can really verge for them .
