Complaint Review: victory secret

for weeks we have been receiving phone calls from this number. Five or more a day, including Sundays. They would ask for a person and we would tell them that person doesn't live here, they would then hang up. If I or another male would answer they hung up without saying anything. Eventually my wife (didn't actually lie) responded like she was the person they were looking for. That's how we learned it was Victory Secret and they were trying to collect money due. We don't have an account with them and we don't owe them money. When they discovered my wife wasn't who they were looking for they hung up on her.
Sunday morning I stayed home because I wasn't feeling good. They called in the morning. I first said, "Do not hang up, we need to know how to get back to you, so if we find this person you are looking for we can tell them how to get back to you." The person gave me the phone number, the bank name, and company name. When I said they needed to change the number, or just stop calling he told me they would not unless we gave him the phone number of the other person, which of course I can not.
I waited until today, Monday, and called them back. I was told there was nothing I could do about it and then they hung up on me. I called back and the second person said they would see what they could do.

I don't know what they are doing. I don't know if they are trying to bill me, too. I do know that they have been harassing my wife and I for over a month now.
