On multiple occasions, MS Service of XXXX WY have tried to contact me at work. Not only do they not verify who they are speaking to before they tell who they are, but they have been told on numerous occasions ( the most recent being today XXXX/XXXX/15 at XXXX XXXX ) not to call at work. The women who calls even started the conversation with I know you told me not to call at work so I will be quick. They havent even sent letters or called my home phone, just harassed me at work.
