EHCP deadline passed

Hi. 

So we got a 4.5 yo, mostly non-verbal, very limited speech understanding child, still in nappies and a pushchair. We got a diagnosis privately (in a hope this would help him and probably us, yea, I know, how naive!) about a month ago, as the waiting list in our area was over three years. The ehcna was initiated at the beginning of spring, and it seemed like we might just be in time before September, when we need to start at the local mainstream. Now, the deadline that was given to us was this Saturday (not even working day - why?..) but it obviously has passed and no changes there. No decision, nobody got back to us, nothing.

What do we do next? This is exhausting, knowing you're completely on your own, trying to reverse-engineer and make sense of a system, where components aren't visible or obvious.
