Extremely  poor customer  service 
I upgraded a system in January.  Since then I've been requesting an updated invoice that accommodates the insurance discount.  I've sent numerous emails and made numerous calls, without any resolution.  <br> <br> My latest statement shows that the account is in arrears for more than 90 days  which affects my credit rating.  This annoys me! <br> <br> I keep on receiving  bills for the incorrect amount and keep requesting  the updated invoice but it seems that no one at ADT can assist! <br> <br> Come on  ADT, do  I need to check out Chubb? Your motto is  speed to be  \always  there ":(<br> """
