how long it takes to get the reciept number for my H1B extension

My lawyer has filed my H1B extension on June 2012, but until now my employer has not gotten receipt number and even the filing check has not been cashed out by the immigration. Whereas, my H1B got expired today, so what should I do?

I am currenlty in the same situation. Did you get the receipt number? Was yours premuim or regular? Is it legal to stay w/o getting the receipt number but send the application after you H1B expired. Please respond as my visa expires on 29th Nov and still havent got any reciept after fling on Oct 25th.
