No need to delete lol
No smoke alarms because of house alarm....
Why would you want an engineer to fix it? Because you can't fix it?
No one mentioned if you can "afford it" millionaires do the same, I said it's about paying
As above you said it not me "if it's a simple fix why would I want an engineer to fix it" , was it a sparky you called to fix and said might be keypad or neighbour? Because you thought it was simple fix you called someone
Anyhow don't take it all to seriously , like you said "you have no idea"
Your definitely at the stage you need to call a professional or very competent person , I am often told that lol
