Strange message from INS

Hi,I got a message to my Cellular phone from INS this afternoon. This is very strange. I submitted NIW and Eb1a at the end of Dec.

The message is : We already resolved your case, but we will extend to June 2 to notice. This is so strange, they did not mention what is the case number and what is the result, just use the word RESOLVED! What does this mean? Denied? Approved? Is there any friend who has the same siduation? I am so nervous about this message.
