Simple Duplicate Transactions Investigated Over 2 Weeks

Hi I have been patient with your Team and I am now gatvol. I have a credit card with you, Monday 6th June I called you guys to reverse transactions that were duplicated and declined by Pick N Pay. Your team asked for proof which I sent last week and receipt confirmed, I used email *** .Now everytime I call since last week I am told IT of admin team is Investigating, there are 4 Duplicate transactions same amount,how clear must the system be to reverse these 4 transactions. My other banks reverse them without even me asking. Please resolve this because I am about to just go crazy all over other social media and other escalation platforms.
