TERRIBLE SERVICE

Very poor customer service, been sending emails with no response, escalated the matter to one of their sales person who signed me up, no resolution. National Security only chasing sales to sign up new customers and once done ,you are at your own . Although I have signed agreement for my alarm system, every month I have to chase after them to debit the account for monthly rental as per contract signed, after reminding them now they have duplicated their debit order deduction, this is a monthly challenge as a customer you have to follow up on their incompetence and irrespective of bring the matter or errors to their attention, you will never get any feedback or call to discuss the matter, very poor services overall. If there was zero star, this what they deserve.
