Unfortunately I don't have any progress to report so far. I got an initial response asking for more evidence of all the times I spoke to Eon and all email chains and that if I didn't submit this evidence within 10 days my complaint would be closed. I submitted this evidence before the deadline and my complaint was still closed.
I queried this and was told it shouldn't have been closed and they would open a new one but that they needed to allow another 10 days for additional evidence, and i am currently waiting for this period to finish.
