Deceased estate not being treated as it should

Registered an Estate of my late Mother in July. To date the accounts are not freezed and still they deduct bank charges on a monthly basis. Why the effort to go to the bank to do these things and 8 months later nothing has been done? And suddenly it is nobodies job to do this. How on earth can they not freeze a bank account of a deceased person? What I would like to know are they paying back the charges they deducted for 8 months? Now I must take time off again from work to sort out this kind of nonsense. Does people not have pride in their jobs anymore? Absa service is just useless. I will never recommend this bank to anyone.
