what to do after admitted

[pw350]

I got my decision from dean of graduate division, however i have never heard anything from the department, no interview, no email, no phone call literarily nothing. The letter i got said funding decision will be made by department. I am concerned after i heard there were PhDs self funded for the first year. I wrote an email to poi i listed in the application form and no response as well. Any advice? Thanks

I would try contacting the department DGS (Director of Graduate Studies) instead of the POI. They might be more helpful/responsive.
