SASSA R350 Grant Identity verification process

I lost my job and then I app**** for the R350 grant in June. In July when I checked my application status was pending for June and July. Later in July when I try to check my application status it I got a message saying I need to do an Identity verification process to finalize my application, I need to request a message that can take up to 2 days to arrive then I need to follow the link on the message to complete the verification process within 3 days. It's been 3 weeks now but I don't receive an message, I always re request the message but nothing. When I try to call the SASSA number they just say all agents are busy I must try again later and drop the call. I don't know how to contact them because I don't even have money to go to their offices.
