ACCOUNT INFORMATION INCORRECT!

I have recently been to two different FNB brances to amend my personal information as I had divorced my husband. Both times I provided my divorce certificate, proof of Home Affairs Name Verification, certified copy of ID and proof of address in order to authenticate myself. However, I am still receiving correspondence in my previous married name. Furthermore, I've now received my E-Bucks to which my new partner had to receive on my behalf and discovered it was still on my previous married name. The incompetence of employees has now had a serious effect on my life and I wish to make it public that your staff can't act on simply instructions despite being provided evidence of such. I had also contacted my premier banker who advised me that my details are changed on the system, yet my new card reflects my old details. I want answer immediately!
