I applied for a comenity card through Forever21 (big mistake). I had a total debt of $300 dollars on that account. The customer representative took down the wrong address and name so I never received a physical credit card resulting in not being able to make the payment. I had to leave country for a month and I couldn’t receive any calls from comenity resulting in a 60 days late payment. My credit score plummeted from 715 to 533 (Feb 2024). I am trying to get my credit score up. Despite my $2000 spending every month on my Amex card, my credit score has gone up to 581. I moved to US in 2022 so I don’t have a long payment history. What are my options here? Should I contact comenity? Or should I try to contact Transunion? I’m worried that I will get not get an apartment now that my lease is coming to an end.
