ADT Mississauga

I'm still in shock that it takes 20 days for ADT just to send a technician to replace my faulty ADT thermostat. The thermostat stopped working on Aug.23 and I called customer care to fix the problem. The airconditioner stopped working as well due to this issue. They tried troubleshooting online but that did not solve the problem. I was then routed to the service team to schedule a service appointment . This is when I was informed that the earliest date a technician will be able to visit my home to replace the thermostat was Sept.16. What??? I couldn't believe that ADT had such terrible service. Are you kidding me!! Really??? Does it take 20 days for ADT just to attend to a service complaint?? Does ADT really care about its customers? From this experience I don't believe so. This is purely very shoddy and unprofessional customer service. I can understand if this was a small company but for ADT to have this sort of customer service is just totally unacceptable. Is there no manager or top management looking at these sort of issues and wondering if they should improve or nobody in ADT really cares. We have been put to real hardship without the air con working in this hot summer. ADT you have lost my trust.
