Can I get help with Facebook here?

I have been trying to set up a Facebook page in order to sell some jewelry and toys. I've made a mess of it and have been trying to fix the mess. I've followed every link I could find that might help me clean this up and even hand-written a letter to Facebook for help...all to no avail. I am hoping someone in here can help me.

This is the mess:
I initially started signing up with a name I want to use to sell jewelry, i.e. a webpage site I will be setting up called "motdaugrnds". Facebook needed a "last name" so I put "left blank" in that spot. I used the email address I want connected to the selling of my jewelry and toys and thought the page was set up, though I couldn't find it.

Then I thought the reason I couldn't find it was because Facebook wanted me to use my real name to set this page up; so I started over and put my real name in the two slots (first name in one and last name in the other). I got message I could not do this because the email address was for another account, my motdaugrnds account of course.

So I tried to log into the motdaugrnds account again and got the message Facebook thought the account was fraudulent. When I take the steps to verify that motdaugrnds account is mine, I get the request for my telephone number; and when I give it, I get the message I will receive a "text" shortly with a code I can use to complete my verification of the account.

Well, the only phone I have is an old fashioned dial-up table-top phone; and of course I cannot receive text messages on that. So I am stuck

Can anyone in here help me straighten this out? I'ld really like to set up a Facebook page using the "business name" of "motdaugrnds", which is a name I use for all my internet transactions. (It was created years ago when mother was alive: mot = mother; dau = daughter; grnds = grandson. This is a combination of the 3 of us who homestead together. Mother when she was alive, myself as her daughter and my son which is her grandson. The name means much to me.)
