Absa ***** Division useless

How does Absa deactive my mothers sms notification when there's money in the account, ehen we ask them to reactive the notification service discover unauthorized debit accounts for MTN and Vodacom which she has never had accounts with.

Absa then asked her to open a case of *****. After a week of investigation, Absa declines to pay bavk saying we must take it up with service providers. How did they access my mothers money which was with Absa in the first place. Why did they deactive her notification and does Absa refer me to a service provider she's never had a contract with. Absa i need a response urgently thousands of rands cannot dissappear under the banks supervision?? Its unfair and *****.
