Pathetic service - 3 months and still waiting to close a dam account

I have submitted all required documents to have my late mothers savings account closed in October last year, the account is suppose to be closed and funds transferred to the estate late account. To date no correspondance was received. When i called last year they said they short staffed. This is the most pathetic bank and will not recommend them to handle any estate late matters. They deducting bank charges each month but they not doing their job by closing the account and doing the transfer.
