hostel fees issue

I have a query regarding the hostel registration fee. I paid the hostel registration fee and Security Fee through the 1-Bill Top-up method mentioned on the security fee challan that someone at the hostel management gave me. However, I noticed that the 1-Bill payment references/suffixes differ for the different fees. Could you please confirm whether the Hostel Registration Fee was supposed to be paid through the Admission/Security Fee challan or through the separate Hostel Fee challan? If not, then which office should I visit? Because I got the hostel, and I do live there now. I have emailed the FC challan email, but I need to get this sorted quickly. Also, my Empower isn't showing anything, but I got the email for the 1st installment. so confused fr
