Received a letter from this company on 4/5/21 about a medical bill. I immediately called and spoke to someone on the phone and disputed this alleged bill. Told her I had been disputing this bill with the medical provider since I was originally billed by them , she stated yes , I see scans where you sent them certified letters disputing this bill I will have it investigated and someone will contact you within 7-10 business days. I received no call, no letter ... nothing from this company . I received an email on 5/1/21 from Equifax that this company added a collection to my account on 4/29/21. I disputed this alleged medical bill with them and the original medical company and they still have the time to add it to my credit report but not call me back ? How would the principles of this company like this to happen to them ? I don t believe James Blair, Marsha Blair, John Blair, Elizabeth Skains or Michael McCeney(Manager) would appreciate an item showing up on their credit reports for something that s clearly in dispute . As quickly as you did this to me with no hesitation or forethought the same can be done to the aforementioned above just as easily I assure you.
