This agency made no attempt to contact me prior to posting a debt to my credit report. I had no idea I had the debt with the company. I called the company to discuss the debt when i saw it on my credit report on May 24, 2021 and the balance was reduced by $160. 374 to 214. This company made absolutely no attempt to contact me. They claimed to have received my account May 16 2021, but the account was opened March 16 2021. I believe this is illegal. Their failure to contact me prior to posting this on my credit report was not only wrong, but unethical. Their decision affected my credit score drastically. However, I resolved the balance and hope this sort of action by this collection agency is addressed.
