Nest thermostat stuck in setup

[Hans33344455]

lost connection to WiFi 

then connection to heat link 

Did a hard reset 

Now it’s stuck in setup , at equipment stage thermostat will not find heat link 

I have done a total re-wire and reset 

Tried everything but still same issue 

The nest is only a year old I’ve had no issues up to this point

Wow 

terrible customer service google , I’d like to escalate a formal complaint 

The response has been very poor and you keep demanding information of which I have already given and say the serial number given is incorrect yet I’ve provided photos proving it isn’t 

can you explain what’s going on
