It was cuz!

I thought someone was terribly mistaken and is collecting money from me.  I got a call earlier telling me about the money I owe her and that I should pay.  I told the caller that I don't remember owing someone some money, the caller suddenly laughed.  Annoyed, I asked who she was.  It was my cousin!  She was testing her voice changer.  She said she got one because some of her clients owe her money and she's having a hard time to collect.  Every time she calls they pretend not to be there.  She thinks a voice changer can do the trick.  Well, good luck cuz!
