Terrible service Damelin

I have been requesting from Damelin my diploma since 7th July 2025. No one is attending to my query . I Was referred to Tebogo Kekana who has been no help. Tarryn Zank , Meena Kanthan and Amanda Paul who have all been no help. Very disapointing service from Damelin as i am ephasising that i need my certificate and letter as to not miss application deadlines.If someone knows the Dean's email or an escalation email please assist.
