Oustanding PDLs

I did receive a follow up letter from one of the CA's within the 5 day window. Is this an appropriate follow up? BTW CA's do not have to licensed in VA. They have to be licensed to do business in the city/county where they are located. However, a foreign corporation, limited liability company, business trust, limited partnership or registered limited liability partnership (i.e., organized or existing under the laws of a state or jurisdiction other than Virginia) may not transact business in Virginia until it obtains a certificate of authority or certificate of registration from the State Corporation Commission.

To Whom It May Concern:

This is to inform you that I've recently received a letter from your company regarding an account with VIP Loan Shop. This letter is to inform you that I would like a verification of the debt and your ability to collect this money from me.

Under the FDCPA, I have the right to request a validation of this debt. I request that you prove that I am indeed the party who is contractually obligated to pay off this debt.

I hope you are aware that reporting any invalidated information to major credit bureaus may constitute defamation of character. In addition, you must also be aware that until you validate this debt, you cannot continue collection activities or report this information to the credit bureaus. Non-compliance with this request may land your company in serious legal trouble with the Federal Trade Commission (FTC) and other state/federal agencies.

Please attach copies of the following documents:

• Agreement with your client that authorizes you to collect on this alleged debt.
  
• Agreement that bears signature of the alleged debtor where he promises to pay the original creditor.
  
• Complete payment history on this account, to prove that the amount you wish to collect is accurate.
