I volunteered for my package and I received a collection notice from T from my last check for inaccurate payment. It was only $145 but still, it’s the principle.
A little tip for people on this blog, let it goto collections and you can get the collections agency that T hired to drop the amount you owe by over 50%. In addition as long as you call and pay the agency within 30days from receiving the the letter it does not impact your credit score.
