Keeps calling me and hanging up. One day, they called about 3 times within 3-4 minutes. I finally blocked my number and called them back since I couldn't find anything by looking up the caller ID info. Outgoing message identifies them as MRS Associates. I've looked them up on buddhibbs.com, and they are one of the worst collection agencies in the country. Document every call from them, and do not deal with them if they are calling you. They are violating the law with how their number is displayed!
