The backstory:I had an account with Vonage for several years. It was paid automatically by debit card. With some difficulty, I closed the account. Also, for unrelated reasons, I obtained a new debit card so they were no longer able to charge me automatically. Vonage attempted to charge me for the month after I cancelled the service, and they sent my account to a collection agency. In summary, Vonage placed the account with RMS. They claim I owe $37.59. I believe I don't. I sent them a DV letter. The original: My DV: They responded with a letter and what appears to be some kind of computer generated vonage internal statement showing invoices and payments (debits & credits). And the following cover letter. My questions are:The DV response appears to say that "M***h S***e" is the creditor. Do I have a violation?The DV response contains the name of the OC, but does not specifically state that Vonage is the OC. Did they fail to validate? Do I have a violation?The DV response did not contain the address of the OC, or any address other than that of the CA on the letterhead. Do I have a violation?What should my next step be? I want to tell them why I think they are wrong, but I'm also leary of admitting that the account is mine. It sounds silly to say "The account isn't mine; I don't know who you are, and by the way, I cancelled the service the month before." Maybe separate letters to the CA and OC? I'm considering something like: Thank you for this wonderful resource you collectively have created, and thank you in advance for any helpful replies I may receive.
