received automated call, don't know whose no. this is

This person called our office asking for someone who doesn't work here. I said they had the wrong #, and they went on and on about how this person put this number down, who is she, etc. They wanted to talk to HR, which is my department and then they just kept going on and on for a termination date. I said, I can't give you one BECAUSE SHE NEVER WORKED HERE. He wouldn't let it go, so I hung up.
Good God! What part of "nobody here by that name works here" is so freaking difficult to get through their thick skulls????

Called about someones prior account with Elastic, a payday loan company that charges 300 400% on payday loans and then get mad when someone doesn't pay them on time, do urself a favor and never get involved with these companies in the first place, its better if they just have no customers at all, because they are super greedy and always call.

This number has been calling me repeatedly.  It is getting really annoying.  I recently found out that it is for a payday loan company called Elastic?  I never received a payday loan from them.  I am already trying to fix a bank account where someone stole $2000 from my husband and I.  I do not have the time or money to deal with this. I am disabled and unable to work at this time.  Stressdoes not help my situation either.  Please stop these animals from preying on decent hard working individuals.

this is twice i've been contacted by these people and they would not say who they are calling from, isn't there anything can be done?
