Prevent access to funds!

My mother need urgent access to her 90/10 investment account which allows up to R100 000 immediate access. She has NEVER withdrawn in 13 years! Today the branch informed her there are a hold on her account but could not explain what. We phoned ABSA ***** this afternoon and they confirmed there are NO hold on the account! ABSA is putting tremendous pressure on my eldery mother who need urgent access to her funds. We were also informed by the branch there is a hold on two accounts of hers. This better be sorted tomorrow or this is going to network24
