Sent money not found in the account with no debit order.

I sent my mother money yesterday for emergency and she only was able to get half of the money from ATM but the sms reflected the exact sent amount. The other half is gone. She went in to the branch, Maake Plaza outside Tzaneen and was told that the other half will come in later. I never heared of such from a bank, what kind of a Joke is this! I want my money back! 😡
