Doorbellfactory.com / These people are scammers!
I have purchased a wireless doorbell from DoorbellFactory website. It took them forever to deliver my order but at least I got it.
I've installed it myself following all the provided instructions. Everything was fine, but about a week later it stopped working. Tried to fix it myself with no luck.
I sent them a message asking for a refund but they did not reply. Then I called and they promised to resolve my issue as soon as possible but they did absolutely nothing. And after that they ignored all my calls!
