No feedback and no action

I bought something on OLX that turned out to be *****. I paid on the 27/01. 29/01 I went to ABSA to reverse the payment urgently and immediately. They said there was time and it was possible but I had to send an e-mail. I reported it on 29/01 via e-mail and instructed ABSA to do an urgent eft reversal. On 03/02 I received an e-mail stating: Account has been blocked please send the SAPS case Number and affidavit. This I sent through on the morning of 05/02. Eugine Galane contacted me and said than an investigator will contact me. On the 12th I sent and e-mail inquiring as to what was going on with the investigation. No reply. Somewhere between the 12th and the 22nd Eugine phoned me and said that I did not send the information required. I told him that it was done on the 5th already and that he must check his e-mail. He did this while I was on the phone and told me that he found it!! He again told me that an investigator will contact me. On the 22nd I again sent an e-mail to Eugine. No reply and nobody contacted me regarding this investigation. I went to the branch and they only gave me another e-mail address. One month later and I have not received my money nor any proper assistance
