Left a stern recorded message about "an important matter that has been pending for quite some time" and that I have been given "ample opportunity to resolve it." I got this number a month ago and haven't had any bill problems in my life. Update your records and go to hell, kthxbai.
I have been receiving calls from this number for a while now and have no idea why or what the heck they're calling for! The messages are always from a automated system. I don't want to give any of my personal info over the phone for them to identify me. If they called they should already know who I am! They always leave reference numbers. Makes me nervous but I truly wish they'd stop already!
