Respected sir, Mam,
My name is Mounica I'm a pharm d graduate. I have applied for OD and CMM 1month and 1 &month back respectively. I haven't received them to my postal address yet. Please let me know how much duration does the process takes. I have checked for tatkal also during application. And I have paid double amount. But didn't received my post yet.
Please resolve sir.
Thank you.
