They called but wouldn't tell me who or why

I just got a call from them on my work phone. I never give this number out to anyone. I do occasionally get calls for other people (wrong numbers). When I answered the caller hung up. Interesting.

They called  on my  phone number many time?

They are a company called Pinnacle Financial Group and claims to be a collection agency for Empi. They called before trying to get me to make a payment but I told them to call me back this week. They called and I told them I need an itemized statement and the phone number to Empi, since I could never reach Empi before it went into collections. I also told her I need them to send me the different ways to pay as I will not give my debit card over the phone. She got irate and said "you told me last week you would make a payment so what has changed between then and now!" I said, "just what I told you! I will not give you my debit card over the phone! There are too many scams out there." She said, "it's just $30!....blah, blah, blah,". I hung up after she insulted me with "just $30". I have never gotten anything from Pinnacle and all of a sudden they call me wanting a payment.
