Lack of livechat response from customer service

I am facing an issue integrating my greenstar 4000 30kw boiler with my wired thermostat but It is relentless trying to get hold of Tado customer service. It’s a disgrace how poor their after sales support are.

Currently, I wouldn’t recommend this company to anyone for their house, and if there are any technical support people from tado reading this, please don’t leave valued customers hanging.
