Give me my refund!

My ABSA bond was canceled on the 28th of February. On the first of March my debit order still went off of my account. I have asked them when will I receive my money back for the bond and they confirmed it will be refunded on the 11th of March. On the 11th of March I still haven't received my money back. I sent an email to follow up. No reply. On the 12th I called and they could not assist woth the refund as it was with the cancelation department. On the 13th I sent another email with no reply. On the 14th ABSA rep**** stating the refund was done. I have asked for the proof of payment as it is still not in my account. They have not rep**** to the request. I have tried to call them on the 15th of March with no answer at all... if the refund in not in my account on Monday I WILL go to the ombudsman.
