BIG MISTAKE – After years with your company, I made the mistake of listening to neighbors bragging about ********. I should have investigated better prior to giving you notice. After dealing with ********, they admitted that they could not offer any savings to me, based on my GRE history. I have cancelled further business with ******** and hope that you will consider re-instating me to GRE so that I can resume our business energy-saving relationship. Please let me know at your earliest convenience.
