I have read the 'must be issued in two weeks' things in a few more places since I was last on this thread, so I think you are well within your rights to put it in writing to them. It's an idea to do that anyway to be honest, as it's all part of the paper-trail. (evidence)
Our LEA insisted the two weeks was for them to produce it, not get it to us. As it happens they even missed that deadline by a day and wouldn't have done a thing about it if I hadn't called and spoken to a lovely lady who wasn't our Statementing Officer, but who realised they were potentially getting into dodgy territory - not least of all because our SO wasn't actually due in for the rest of that week.
She arranged for an admin assistant to email it to me the next day, albeit without the appendices. They then put it in the post the same day, via some obscure non Royal Mail service and it took a week to arrive.
Thing is that they then told me that our 15 days response time started when they finished producing it and not when we actually received it!
So we had already lost a full week of time to read, review and amend it (including meeting with the school) by the time we received it. The school was exempted from including the Easter holiday in their response time, but we weren't, so I had to return it without liaising with the professionals about a few things, because no-one was available over the holidays. 
We still haven't received our second (amended) proposed statement and the deadline for the finalised version is in less than two weeks, so we're in a similar position of having to push the LEA.
Best advice I can give you is to put it in writing, as well as email to them and keep pushing.
