Call Centre onhold for 2 hours no reply daily

I have been trying to reach Unisa since April, at first the University was shutdown due to the lockdown, and since I will be on hold for 2 hours. Countless email sent to them, no response, and all I need is to access Mylife platform I changed contact numbers and can not receive sms with new password. And I even tried requesting an Academic record, no reply for the past 3 months.
