These people call me almost EVERY day at work.
I notified them back in August that the ONLY contact I would have with them was via US mail.
I have emailed them repeatedly and told them in person that they are NEVER to call me at work.
This morning, I hung up the first 2 times they called and the 3rd time had someone else answer. They left a message on my voicemail. These messages are also my proof that they are harassing me at work.
I also noticed that every time they call it's a different person-so that you won't know who it is and answer the phone.
