XXXX/XXXX/XXXX received debt collection notice from Dynamic Recovery Solutions. I responded on XXXX/XXXX/XXXX asking them to validate the debt because I have never had a creditor by the name they indicate and I have never owed a debt in the amount indicated by Dynamic. I never received any response. Then on XXXX/XXXX/XXXX they sent another collection letter. I still have not been provided the information I requested and I have advised that this is not my debt.
