Who called from 2560000000

This morning my fiance received a call from this number and the lady said it was a wrong number then I received a call from the same number about 5 seconds later and she said the same thing.  We live in Michigan as well.

Got a call on my cell phone today a 3 15 pm. Did not answer. No message left. Lansing Michigan.

I'm in Lansing too so they must be working this area code today.  I got the same call from the same young woman and the same 'sorry, wrong number'.  Call at 3:27pm.

i just recieved a call like this we are in michigan also and she said im sorry wrong number and then she hung up, 10 min later they called my home phone but i did not answer

Received a strange call on my cell in Northern Michigan (like everyone else) female voice says, "Oops, I have the wrong number!" and then hangs up.

I am on a no-call list for my land-line and cell, wonder if it is computer generated to determine if numbers are valid or working numbers?

Had me curious anyway ... I'll be paying attention to my phone bill, too.
