sat sri akal geet dhillon . All you can do now is track and follow your application. I had sent the payment too to the university for first semester which got updated almost next day. I kept on communicating with the university on day to day basis via e mail to ensure my payment gets updated. In my opinion you should send e mails to admissions deptt of gbc . E mails are generally answered in a day or two.
aint no expert.. my opinion is in non expert category
