Pierce Terrace Elementary School

I received a bill of 556.07 today my son has not attended Pierce Terrace in 2 years! I lived at Fort Jackson for 3 years I'm not understanding why no one contacted me about (which they still haven't). I have PCS'd and It blows my mind you would send someone a collection notice of almost 600.00 with no prior bills phone calls letters etc. I am so freaking hot right now you will be getting a call from me on Monday! I work everyday there is no way I would let any of my bills get to the point its in collection shame on you guys for such communication and underhandedness.
