Poor aftersales/technical service

Last year i upgraded my home security system at quite a cost. I had been with ADT for about 5 years and their old system wasn't working. There is an app that you can use to see if the alarm is on etc. A few weeks ago i noticed that the app was no longer on my phone. I downloaded the app and on opening it, there is nothing on my profile. After a number of calls and an email to ADT i got a call from the technical division and they tell me that i need to get a technician out to my house at a cost of R 580! To set up an app??? Seriously? They can't just help me over the phone? I am sure they can, but that wouldn't make them any money. I have no issue with their security staff in our area, they do a very good job, but their customer service leaves a lot to be desired.
