Under Debt Review and still being double debited

I was double debited and I'm under debt review. I spoke to a lady Monday 18 December at 10:27 and she advised me that the funds will be refunded and that she will sort it out. Today i spoke to Lindi and she advise me the is no record of that call. Now this is so a big inconvenience to me as my medical aid will be debit returned. I was send all this documents to complete and have to send it back to only cancel the debit order now. This is so ridiculous. Can someone please sort this out correctly please and have me refunded asap please?
