Capital Accounts, LLC Debt Collection Complaint

Capital Accounts, LLC Debt collection department,

I do not know Written notification about debt Didn't receive enough information to verify debt Florida

Have sent a letter and three emails asking for validation of this debt. Asked for signed contract and proof they legally had right to collect debt, along with bill of sale. Have not received any of the aforementioned documentation. The only item that was mailed in response to my request was a two sentence letter advising how much interested has accrued. No proof of the account has been supplied what so ever. Informed company on my third request that I would be reporting them if continued collection efforts without supplying documentation, I received another collection letter yesterday, still no documentation.
