They are calling from Weltman, Weinberg and Reis. It is a collection law firm. They do collections for many companies. In my case, it is Capital One credit card. If you do call them, be aware that they record everything.
They are bottomfeeders not to be taken seriously. Report them to the police if they harass you. Record everything as well. If they call to harass me I will call and harass them back tenfold.
This number has called me three times already so I block them on my phone and I also add them to a spam list so when my phone rings it will be identified as spam but I still won't answer they need to stop calling me before I really get mad they need to leave me alone and do not call me anymore.
