Student loan debt related

Student loan consolidators. Will text me from random 5 digit numbers
This is the voicemail I got... i don't have any student loans.. haven't gotten a few texfs. I opt out every time still get them
"This is the National Student Debt Agency calling to inform you that your student loan is pre-approved for a lower monthly payment or possible loan forgiveness. Call now at 970-458-1140. The number again 970-458-1140."

Yup, definitely a scam. I don't even have a student loan and I never even applied for one, ever.

Don't have a student loan... Blocked the number

Message left from the "National Student Debt Agency" to inform me that my student loan is pre-approved...
