Old age grant not paid

I am writing this with. Such disappointment of old mutual bank, my mother who is a pensioner, Saa grant recipient has not been paid this month. This is an old lady on medication which requires her to have food before medication. We have been making follow up at Bronkhorstpruit the whole of last week, all ended on empty promises. The whole nightmare started after account holders were told to change cards and my mom was one of them. She is starving, borrowing money to send my sister to town daily for follow up and no one cares at old mutual bank. How is she supposed to take her medicine without food?. What will it take for her money to be paid?
