Bad service

I made n payment of R1338 from my discovery account to a 3rd party (Vox telecom) and the payment did not reflect in there account from 4th of December 2021 till today I have not received any feedback from discovery bank. I have my case number and all was send to the bank but no one can give me answers. I have spend more money on phone calls to discovery than I can say. I won't be using this bank ever again
