I received a notice from United Online Collections Division saying that I am passed due for a Net Zero payment of $29.90 on Acct # 867938752589. It also says that if I do not pay in full by May 25, 2009 or notify them that it is in fact a valid debt, than they will assume it is valid and it will remain outstanding. First of all, I have not used Net Zero for at least 1.5 years. I have not received any bills for this passed due amout AND I cancelled my account with them over a year ago. I will not pay this amount. It must be some form of a scam. read full review »
