A shortened, blank or partial payment history could be the result of a having a new account, as payment history is not available until accounts are at least 30 days old or due to recent improvements made to ADT's billing system, which may have affected the availability of your account payment history. These changes have no effect on billing amounts, but they do prevent the MyADT.com account portal from displaying them for some customers. Please note that a payment not displayed is not an indication that ADT did not receive the payment.
