Postbank Customer Service Failure

Very Frustrated! For the past two months, we are unable to get my disabled daughter SASSA grant. We used to get it monthly through the PostOffice, due to PostBank card issues, new cards were not available and now we struggling with the call center, calls are simple dropped, had two previous links but both were not successful and emails for assistance not successful. Postbank and SASSA is failing its people with the most vulnerable people impacted.
