Capital One Credit Card Complaint

Capital One Credit card department,

Identity theft / Fraud / Embezzlement Florida

I received a letter from - stating I had a balance from a capital one credit card. I asked them when this was opened and to send me the proof that this was my debt they said it could take ninety days I responded with you have thirty according to the law that is enough time for you to get me the information. They then sent me a letter 36 days later without proof the debt was mine and said they had just opened an investigation into the matter thirty days later. I called in response to this letter and asked them to stop their collection efforts and to remove this from my credit file immediately since they could not provide the necessary information in the time slotted.
