Harassed over a paid account

I received an email today from this company stating that my COJ account was not paid up when in fact it was paid up a long time ago. I called them and the person by the name of Walter indicated that I am the 3rd person today that complained about the same type of issue. Their email indicated that they have tried to contact us but could not which is not true.<br> <br> I view this email very seriously, it is harassment and a question of my financial status. Someone needs to stop this company from sending out false emails. <br> I want a letter retracting their email.
