I have repeatidly disputed account number XXXX with the credit reporting bureaus about Ad Astra Recovery Services and their aggressive and frightening collection tactics. I have asked doth bureaus to investigate and validate this debt that I have paid in full with XXXX XXXX and delete it from my account. I do NOT owe Ad astra anything and they have recently been calling my cellphone at late hours and leaving voice messages with a machine regarding this supposed debt that I know i do not owe them. Please investigate their aggressive and illegal attempts at taking money i do not owe them. they have not even provided any valid evidence nor have they communicated properly with me regarding my disputes and request for them to stop contacting me, especially with automated systems. They are so embarrassing and annoying. They need to delete their account from my credit reports immediately or I will contact an attorney. This is my last warning to them. Please help me.
