ABSA DIGITAL VERY BAD

Good Day I sent through an email to ABSA DIGITAL on 20 May 2019 for a EFT reversal. A Case Nr C- ********** 9 was provided. On 22 May I received this message - "Kindly be advised that according to our records this was an inter transfer and funds were successfully transferred back to your Absa account." I have re**** and informed that the FUNDS WAS NOT SUCCESSFULLY TRANSFERED BACK. TO DATE I HAVE HAD NO RESPONSE. How long do you take to respond and to proper solve the problem? Why do you guys not have a contact number? I acknowledge that I mistakenly made a payment to the wrong account number but it is the most frustrating thing to not know what is going on with your query.
