XXXX XXXX of Allied Intertstate has been calling for XXXX straight business days beginning on XXXX/XXXX/15. I XXXX at a high school and she keeps calling me at the school. I have no outstanding debt. I called her back on XXXX and got her voicemail. I left a message stating that I had no outstanding debt and told her to stop calling. The same thing happened about a year ago. She called my work again today and left another message.
