Enlightebned Wealth Institute How did they get my cell number? Provo Utah

Hi,
I just received a call from a "rep" of this company on my cell phone and have no idea how they got my cell number. I have no land line home phone and use my cell for all such purposes but my number is not listed anywhere and my friends would not give out my number. However, I have been dealing with a temp agency very recently as I am looking for work and have found that ever since giving them my number I am getting calls from companies I've never heard of trying to sell me "stuff" I have no interest in and have NEVER inquired about in any way, anywhere.
I called them back (I missed the initial call) and found to my surprise some stranger I've never heard of trying to sign me up for some "Robert Allen real estate workshop" that was coming to my area. I said "No thanks", and hung up. Then I got curious about how they got my cell number and called them back and asked how they got my number and was told, "I don't know. All I have in front of me is a telephone. A friend of yours who has attended the workshop must have provided it for us in the workshop." I told him, "No, my friends don't give out my number to anyone like that and none of them have ever attended any such workshop." I added, "Nor have I ever heard of your company or any "Robert Allen"..., so how did you get myu unlisted cell number?" I couldn't get an answer. I decided to check this "Enlightened Wealth Institute" company out on line and apparently there have been others doing the same as a number of choices came up in the auto fill window as I was typing therir name into the google seach box. The first listed "Enlightened Wealth Institute" auto-fill choice was also followed by the word "fraud". I clicked on that and here I am telling you about the call I got from them.

I have also had to deal with a certain attorney agency lately who soon after that started I started getting calls on my unlisted cell number from some "credit repair" company who again, I'd never heard of or ever inquired about, in any way, shape, or form.

I'm naming the temp agency here just in case others have dealt with them and had the same stuff start happening to them and also the name of the law firm, who by the way, was previously sued by the MN Attorney General, but the judge in the matter judged in favor of the law firm.

The temp agency is called Superior Technology Resources and they are in the Minneapolis/St. Paul metro area.

The law firm is Messerli & Kramer, also in the Minneapolis/St. Paul metro area.
Has anyone had any same or similar experiences?
