Who called from 3015776523

I'm wishing I had answered:

"Oh no, do you need my name and credit card number? OK, here it is: My first name is IMA, yes "I" "M" "A", my last name is - oh just let me spell it for you "D" "U" "M" "C" "H" "I" "T", my credit card number is 1234-5678-9123-4567 and the code on the back is 111. You're welcome!"

This is completely out of control. They need to be stopped! The call was to lower my interest rate.

This number calls me at least 10 times a day!! I am on the national do not call list isn't that supposed to stop these?

I frequently get calls from this number and a couple of times I've stayed on the line and asked to please be removed from their calling list and each time I am hung up on. Rude. My # is also on the 'Do Not Call List.'

How do you get this calls to stop????
