Brand new boiler experience turned disappointing

Purchased a brand new boiler along with a comfort system and a gateway. Unfortunately, the boiler failed within less than a month of installation. It took two weeks to get the comfort system functioning, as the technical support team seemed unfamiliar with it. Additionally, the gateway struggles to connect to my WiFi, resulting in numerous connectivity issues. The technical support has been unhelpful, unable to clarify which products I need to support the boiler. I regret spending my money on this.
