Purposefully delaying people payments

I've app**** for my late husband pension. Have been following up the file until I was told it's on the last step where they confirm banking details and my SARS status ( which took about 4 days) Then I was told the money would be paid out on the 14/09. When I checked payment I was told it's been cancelled due to incorrect account name. What was being verified during the week 07/09 if the banking details would still prove incorrect? I drove 170km to submit the new forms on the 15/09 in Durban. This was only scanned to Pretoria on 20/09. There's no urgency in these employees. My husband ended up dying before his money was paid to him, leaving me in debts and now I have to wait for another year for this money to be paid out. Why so much torture? Call centre supervisor promised to fillow up and revert back to me on 21/09, to date i havent heared from herl
