Pulte Homes Centex Pulte Homes: absolutely no customer service Nationwide

I  called  PULTE   asking  if  they  could  help  me  to  find  out  how  the  wires  in  my  home  are  routed  since  they  have  the  blueprints.  My  home  was  originally  built  by  Centex,  a  company  which was  bought  out  by  PULTE  a  few  years  ago.    I  was  told  to  fill  out  a  "service  request  form"   online.   After  several  weeks  still  no  answer.   I   sent  them  a  reminder  and  this  was  their  response:

"Unfortunatley,  we  are  unable  to  provide  blueprints  for  any  Centex  homes.  These  prints  are  proprietary  of  the   corporation  and  can not   be  provided  to  homeowners.   We  apologize  for  the  inconvenience.

Thank you  and  have  a  great  day !"

For  them  it  is  an  "inconvenience"  to  me  it  means  destroying  the  walls  to  find  the  wires.  They  have  the  blueprints  and  know  where  the  wires  are   but  they  don't   care  at  all  about  customers  and  their  problems  after  a  house  is  sold.
