I received this same call from 441-793-433757.  He said his name was Paul and he was with IMSM.  He would not elaborate.  I went to google and IMSM apparently is a company that does ISO Consultations, ISO Certifications & training.  He would not leave a message and said he would call again.  I'm sure he will and he will get the same results.  Bye Bye.

441-793-433757 - That is the number that shows up for me as well

The girl refuses to put me on the Do Not Call List unless "name of one of my managers" tells her so. I told her she will never, ever, be put through to him and she said she'll keep calling. No longer going to pick up calls from this number.

Call from-(get this)  441-793-433757  Really, was that an extension? No message as you would expect-

Don't get scammed. Don't give out information.

Don.

Man with an British accent called wanting to talk to someone about quality control.  When I kept asking him in what regard, he kept asking me to speak to someone regarding quality control for the business and a quality control license.  This is a mechanical contractor, I'm not sure why he would need to speak to someone here about that.  I can't even remember if he identified himself or the company he was calling from.
