Device doesn’t work. No contact details for support!

Firstly it is INFURIATING that there is no easy way to contact you - and that I am sent on a never ending circle of redirected links to the community bulletin boards when I click on “help” or “support”. This is a shockingly poor way to provide after care to customers once you’ve taken their money for the product. My doorbell rang this morning and there is no footage - it simply shows a blank screen. My live feed won’t play back or display anything - just a rotating circle as it looks for the device. The door bell is charged and is 50cm from the wifi booster which is three meters away from my router, with no wall in between. How can I make this product work? It was totally useless this morning and a complete waste of money. Even ordinarily, when it was previously working, by the time the camera opened the caller had been and gone. Utterly useless. Please provide some help as to how to make this product work.
