Poor service from security company and management

The alarm system was installed in my house and since then i am very unhappy with response from the Security and employees at customer services. i took on ADT due to their promise to us for best security.We had tenants renting at our premises and there was an intention break in and they contacted ADT or used the emergency alarm. The security only came to check up few hours later and this is ridiculous.Why have such buzzer if you going to ignore. You guys had a special and Us people trusted you and you overpromise us and under deliver.The tenants did mention they will not make payment due to poor service and you guys excepted this.This simply means that there is an over signed amount of people and not enough security on duty to attend to an emergency.I am now in a situation where i should pay for poor service or no service at all.I received several sms and i contacted the call centre numerous times and askd to speak to Zandile as per sms .She has not contacted me to date with an email address and now i am held responsible for payment and threat that i would be handed for debt.Keep to your word...stop bull ****ting people its *****.
