Smart Home plus app not working

I already mentioned in my post that App was reinstalled dozens of times along with talking with dozens of helpline personnel at backend, customer care and tech support who mentioned that everything is properly linked and working at backend. Your support persons give the stupidest of reasons for app not working. One reason given to me was that since I cancelled a maintenance appointment (of internet service) so this is happening because of it. What a lame tech support you have? Two other persons kept asking to click the “question mark” icon on my app when I told them several times that there is no such question mark. They were probably used to android app and not the iOS version of app. I had to tell them the steps about how to use this app and get connected with the dedicated team responsible for this app. They were supposed to know this. One person in tech support asked me my password and then used it to login at his computer/developer version of the system and said there is nothing wrong and your credentials work properly at his end for smart home security plus. I tried it in multiple phones and on multiple networks and it gave same issue. Your software team who developed this crappy app needs to make the app bug free before releasing it. I got rid of it and discontinued my service as for weeks I was charged money without even being able to login to the app a single time. What a horrible experience. Horrible customer service
