Account in Estate status when person is alive - shocking service

My elderly Mother went t ABSA in Lambton to reactiate a dormant account only to discover that the acount is under estate ie according to ABSA she is dead !! The branch told her to return in 2 days. I spent over 2 hours on the phone with various people today from customer service, to their National Deceased Estat Dept , to their Headquarters and finally complaints dept - All whilst trying to find someone to resolve the problem. It apparently was a "system error" since they have not death certificate (BECAUSE MY MOM IS ALIVE!!!!) and that the branch should fix it. I was sent fom pillar to post. What shocking service all around. Ineffiecient, unhelpful and all round ***********
