Behind on Personal loan when on Payment Holiday

So, I have app**** for the payment holiday (personal loan) in April. It was approved and should come an end, end of July. The problem is, I received a call from NNI attorneys claiming they act on behalf of ABSA and that I am behind on payments. Not to big an issue, I forward them my approval letters from ABSA thinking it is resolved. Today I receive a text also claiming I am behind and must respond to commit or dial a number to make arrangements. Could someone at ABSA please resolve this issue? I am under the impression that normal debits will run from 1 Aug...
