Today I had a response from that looks a bit "hmm, yeah your worry not ours" :
I am sorry to hear that you didn’t receive a response from this campaigner, and I understand your frustration around this situation.
Indiegogo values crowdfunding as a collaborative, community-driven endeavor. At the heart of any successful collaboration is open communication. This is why we ask campaigners to stay in regular contact with their backers, and provide updates on the status of their project and perks.
As with any early-stage project, crowdfunding campaigns may take unexpected turns, which can include changes, delays or unforeseen challenges. While your contribution helps to bring something new closer to reality, there is always the risk that a project may end up falling through, and that the campaign owner may not be able to deliver the perks they'd originally offered.
Whenever a campaign fails to meet backer expectations, we share in the disappointment of the community. However, we will continue to focus on building better tools and sharing best practices to foster open communication and transparency.
We value your feedback and thank you for your understanding.
However, I have also had a response from Amazfit today stating :
Our developers have checked the feedback you sent. We regret to tell you that your watch issue can't be fixed online and it should be returned for further tests.
Perhaps progress, what we already know is that this means it will disappear for an unknown period of time and then be returned mysteriously fixed, I'm suspecting they will argue about postage and it will be a year from when the campaign started until I have a working device.
