It sounds very much like a scam my wife experienced. I can't figure out what they mean to get out of it but it is not legitimate. We had these calls for weeks, at all hours of the day and night, asking for someone who's never had this number (not in the last few years). On several occasions I asked who are you trying to collect this debt for? And the answer was, The Lending Club. I contacted the Lending Club and was promptly answered by a guy in their fraud department, who was very helpful, and told me they do not employ any debt collection services operating out of India using spoofed caller ID. He said this is fairly common and gave me contact numbers for the FCC and FBI. Unfortunately there's not much that can be done. She ended up changing her Vonage number. I strongly suspect that had I ever asked the question "what do I have to do to make these calls stop?" the answer would be something like "just give us your credit card information and we'll put a one-time charge for (fill in some two-figure number)" It's robodialling with operators who get put on the line when someone appears to answer and they are probably getting paid next to nothing. I can't come up with any other conclusion given the facts in my case. It's possible this is the same..
