Wipro — Relieving / experience certificate Not received

I have submitted my system and ID card but still ut shows that the IT proof is pending with tyr employee.
My salary does not fall under income tax hence I do not have any IT proof to submit. However I have still emailed the form 16 pdf format to fnfsupport.hrss but didn't get any response. My last working day was may 9th which got approved on 27th may. It took.time for few emergency approvals for release from wipro
