Product: Debt collection

On XX/XX/year> Sequium Asset Solutions submitted a debt collection to my credit without notifying me of the said debt nor providing any information relating to the debt. On XX/XX/year> I saw the debt reported to my credit and disputed it in writing via email per the call I had with a Sequium rep after being advised for the 1st time what it was for. The email sent can be found below. I never received a response via email or my home address and to my knowledge never a phone call as they had removed the debt shortly after. They violated my rights by not properly notifying me of the debt before reporting to a credit agency and then continued to violate my rights by not responding to my request for them to validate the disputed debt with the information requested below. They had 5 days to respond per requirement and never did. To this day I have never received return communications from them despite providing my address to them and my email address. Again they have placed this debt on my credit without my knowledge ( x2 ) and failed to take their required steps in pursuing this erroneous debt.
