Linux Foundation has violated my digital rights by not responding to my request to delete my account for a long time...

My first request was around June. My second request, followed by an addition support ticket was at the end of July. In both these situations, I've been left without any response - no "hi"s, no re-assurances, nothing.

Unfortunately, I am not from the EU region, neither do I live in one, but given how this also affects the citizens of countries under EU, how should I proceed further? Is there a webpage online, where I can just file them? Or is it only possible through the local DPA/court?
