Caller ID shows Nicholson Rosem 972-832-2241. I determined through another site that this is an unlisted cell phone in McKinney, TX. Male caller said he was general contractor and will be in my neighborhood offering a free roof inspection. I declined his offer. I don't do business with people who violate the Do Not Call list.
Had calls from #972-832-2241 on Oct 8, & Oct 11-14 often followed by a second call from "Princeton, Tx 972-734-5575". Not sure if they're related, would be interested hearing feedback.
