Junk debt collector, don't understand all the sticky note
I'm being pursued by a junk debt collector.
This was a medical bill that was settled and just came off my credit report last month (March).
They are wanting payment for what was left over after I settled.
They sent the letter (an attorney letter) to my mothers home, which she gave to me.
In the letter is says everything the sticky note by Mr. yet said, but I don't understand how to handle it.
Do I ignore them and not contact them or request validation of debt? Or something else?
Can this go back on my credit after it just came off?
Thanks if anyone has any info for me.
