Unauthorized withdrawals

I'm a student currently getting a bursary allowance a month. I received my monthly allowance for May yesterday and at 4 pm I received a notification of a withdrawal of R1000 and another withdrawal of R200 happened after. Note that my card is with me and they said they can't help me at the branch, I just need to create a new card. I'm a student, this is the only money I get, i need to buy groceries, j have needs and now R1200 was "mysteriously" withdrawn from my card? I don't know how I'm going to get through this month. 💔
