In XXXX I realized I was XXXX. I applied for XXXX, and then I applied for XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX, when I was needing help. I was successful in receiving XXXX XXXX XXXX, but, was not successful with XXXX 's XXXX XXXX. XXXX started to make negative postings on my credit. Missed payments of late payments. I was able to catch up with payments with XXXX, but in XXXX XXXX, when I made my last payment to XXXX card service, that was never posted on my credit report. It started to show that I was late with XXXX payment by XXXX then XXXX days. Then, XXXX sent me a letter offering to let me reapply for XXXX XXXX XXXX, I did, and sent a copy of my XXXX award letter, along with proof I had been working at that time, and a Doctor 's signature and DX. Then, I got a letter saying that I was approved for XXXX XXXX XXXX, for XXXX forward and not XXXX forward, ( date XXXX found me XXXX ). Ok, great. I got a check for " fees '' for {$910.00} from XXXX XXXX XXXX, but, no changes on my credit report. Next, XXXX sends me email saying I was not responding to an earlier email, ( which I did not receive ) but because XXXX had closed my credit card in XXXX, I could not access the system. I called XXXX, and a woman said she could fix the credit reporting, but, pushed me to accept ro-bo callings. My credit has still not been fixed. 
I am trying to buy a house and lower my monthly expenses, but XXXX 's years of bad credit reporting has my credit score in the XXXX 's. How can I fix that?
