14 work days now 29 work days and no help

I have been trying since the 25th January 2020 to get an EFT reversed that I made in error. I paid DSTV instead of Vodacom. Reference numbers below from all the bank visits, phone calls and e-mails. Yesterday's response was that they sent it off for further info.

25.01.2020 – I paid money to a loaded beneficiary – Multichoice incorrectly – it should have been paid to Vodacom. I went into Hartebeesport branch on the 25th, where they tried to assist me by calling head office to get the reversal actioned. Head office advised that I should come back on Monday 27.01 as the payment is not through the system yet. (INC – ***5)

27.01.2020 – I went into the branch again and the people there phoned head office again to see if the transaction is reflecting. Head office advised that they have put through the request and I should check up in 14 work days if there was any progress made (INC ***4)

22.02.2020 – I went to the branch again and they phoned head office to follow up on where in the process the funds is – (INC***8)

29.02.2020 – I went back to the branch again, and the manager assisted me as I was extremely frustrated. He phoned the head office who confirmed the funds will be returned to my account by latest 03.03.2020

04.03 INC ***1 - mailed customer care and they escalated

05.03 Facebook messaged not resolved. I am tired of following up and getting vague responses and no resolution
