(Sub) Contractor threathened to put lien in the project house

[Anita Effendi]

Hi,

Anyone has experience in getting letter from a company that threathened to put a lien in the house?

I am working a project to fix and flip; I work with one contractor for interior and exterior. We also did small concrete work that he needs to 'subcontract' ; he said it is a friend of his and he has been doing some projects in the past.

Fast forward few weeks later, I got a letter in the mail requested some 'money that has not been paid', in the amount that almost double that I paid for. I did not recognize the the name of the person that requested the service in the letter so I contacted my contractor and he did not know know who that person is.

The company that sent me the letter is: Robertson's. I checked the Yelp review and they have horrible reviews.

Any advise will be greatly appreciated. Thank you again!
