Transunion Credit Bureau
No change in my score

HI, I've worked so hard to repay and close all the accounts that i had but to my surprise my score is still the same after 7 months. i don't know how this scoring works but it is really messing up my life. i want to buy a house but i cant because of my Transunion score that's 630. all the credit bureaus my scores are over 740 besides Transunion. can i get someone to look at this matte
