Lead time has been delayed

Do not thank me for my patience, because i dont have patience anymore. I have preordered my latte panda alpha with a delivery date end of last month and all i get is a new promise that it will be shipped late of this month. I dont want to wait anymore.
"Lattepanda Alpha and Delta are expected to be available at the end of August."
Now i just get a
"Lead time has been delayed : (
Lattepanda Alpha and Delta are expected to be shipped in late September."

I am now expecting the latte panda not coming this year or ever. Please give statement about precise shipping time.
