TymeBank blocked my account

I advised my mother, a pensioner, to open a TymeBank account because the fees were lower than at other banks, and she would be able to withdraw or deposit money at Pick n Pay because we live next door. She deposited her last R10,000 into the account after opening it, and then BOOM, the account/profile was blocked; the message on their website states that they suspect *****.

By the time it was blocked, Mom was stranded far away from home with no money to return home. We called their call center, and they transferred me to the ***** department, whose phone keeps ringing, the answering machine is not even clearly audible, and the consultants at the kiosk are also clueless. It's frustrating and I regret opening this stupid bank account.
