URGENT HELP PLEASE medical exam

I have applied for my study permit for about a month now and waited for my medical exam package all the while. Strangely on June 22nd i got an email from the embassy with 2 attached files and the email told me i have 20 days to undergo a medical exam. The two files was a letter with instructions and a IMM 1017 section A form. I have confirmed it with my friends that already gotten the visa and they all said they got there package from DHL courier service and the package had a lot more forms. I am worried that this package is incomplete and also i have already contacted the embassy via the same email but still no reply. Does anyone have the same experience? please let me now. also the visa office is guatemala.
