XXXX XXXX moved out of a warehouse in XXXX in XXXX 2015. A new tenant moved in XXXX 2015 and they did not convert the electric account to their name. The electric company XXXX assigned the matter to IC Systems a collections agency. IC Systems contacted us for payment on XXXX XXXX, and we advised them that we are not responsible for these charges. IC Systems continues to harass us for payment and is threatening to blemish our credit and any accounts we have. Attached is a copy of the threat.
