ADT - Poor service delivery

Poor poor response from technical side of ADT. Have had issues with my alarm system since Friday night 22 March and been kept on hold for 20 mins at a time trying to get assistance for over 5 days. Left messages???? No one bothered phoning back. Complained to the manager Kelvin now, lets see what happens? What will I do if someone breaks into my house while ADT takes their sweet time to sort my security out when we pay them for a security service. ONLY EXCUSES with no service delivery and no security.
