They are calling upwards of XXXX times a day, often with repeated phone calls occurring within minutes of each other. They are also switching phone numbers every few days, making it very difficult to get them to stop calling. 

In addition this company, despite having called in excess of XXXX times, has never left a single voice mail message. 

Finally, based on the calling pattern and lack of messages, it appears that the company is improperly using automatic dialers ( ie, robo dialing ), which we have never given consent to, putting them in violation of the the XXXX XXXX XXXX XXXX XXXX XXXX XXXX.
