I disputed an item on my experian credit because XXXX informed me that, based on my agreed terms with them, ones my collection account is XXXX on that day, XXXX, XXXX of the supervisors will inform credit bureaus to delete the collection. XXXX XXXX account was deleted from my account on XXXX, the XXXX. I logged in my experian membership account on XXXX2015 and found the account deleted completely. Some staff at experian put the account back on as paid, and closed on XXXX XXXX. I disputed the information as inaccurate with supporting documents from the merchant, requesting experian to delete the collection account. Experian staff threatened to block me from accessing my account if i kept calling them, Since then i could not access experian account or dispute any information on my report. I am currently denied my basic right to dispute a wrong information on my credit.I am only allowed to dispute over the phone. I am including a copy from the merchant authorizing account to be deleted and confirmed that they did contact the XXXX bureaus and was deleted. I did provide this documents to experian through online and fax.
