Called and left a voicemail about a "personal matter" and gave me a number to call back to resolve the issue. The number they told me to call was for a hospital where I had am MRI done a few months back. I was late in paying the $600 bill so they had called me a few times to collect the debt. This time, they had no reason to call because I had paid my bill 2 weeks ago. A receptionist in the billing department at the hospital said that she couldn't tell them not to call because she doesn't know how to reach them and that the reason they're calling me is because they probably just haven't updated their system. I reminded her that if I've paid the bill I shouldn't be getting any calls at all, and it's their job to keep their records straight, and I would consider it harassment if they called me again.
