I want my money

On the 28 April 2020 I did a R2000.00 EFT from my First National Bank to the “Ithuba Holdings “as on First National Bank list of Public Recipience. I did not insert the Account number as it is already an FNB Public Recipience list. I contacted various Ithuba staff by email and telephone over the past 4 months. I went to my local FNB branch on 3 occasions. The first visit was to get a proof of EFT payment which I send to Ithuba. As this matter can only be solve by FNB and or Ithuba Holdings. I can’t solve this matter as every time the two parties send me backward to each other. Ithuba said “No” FNB must sort it out. FNB said “No” Ithuba must sort it out. Please help.
