Nados taking forever to refund me for the double transaction

Am so so disapoitend with Nados Sandton, i swiped my card on the 18th of May 2023 for R460 transaction went off twice meaning my accoubt was debited twice, i showed the lady dat was assisting me with the transaction that my app is reflecting the 2 amount she said to me the second transaction will reverse, and it never reverse. I had to drive back to sandton the following day to the follow up with the transaction becouse it waa not reversed, Nados manager took my bank statement, and send it to Nados support team, they confirmed that indeed the 2 amount is reflecting, fast forward i havnt receiced my refund till today, and i stay far , i cant drive back to do the follow up, i was in sandton only for 2 days.

Am so disapointed.
