Wrong itr form submitted.

Respected Team members,

For the financial year 2014-15, I wrongly submitted the ITR form. 

Scenario is , i was not a permanent employee. They deduct tax (10%) every month and given form 16a to me.  But today i noticed in the portal that the form which i submitted has been processed with a message no demand no refund. I have'nt received any intimation by email. I supposed to get 15000 INR as refund. Some professionals said i wrongly submitted the ITR form. Instead of ITR4 , i efiled ITR 1 .

Please advice me how to proceed further? 

Advance thanks for your replies
