Unauthorised Credit card transaction with no Feedback from ABSA - Poor customer service!

I would like to file a complaint against ABSA ***** section, and ABSA customer service in general. On 28-02-2024 a unauthorised transaction was done on my credit card for the amount of R8 464.00 I did phone the bank immediately after I saw the message. I reported my card being used in Dubai for an unauthorised transaction. The lady did confirm that NO verification was required for this transaction. I was informed that someone from the ***** investigation department will phone me within 24 hours. Today is 04-03-2024 and absolutely NOBODY phoned me yet. I am a Platinum Professional card holder at ABSA and I emailed my Priority banker, and enquired why the transaction went through without verification needed as per usual. He stated that it SHOULD have requested for an verification, but did not elaborate on how it could go through without this verification. He also just referred me to contact the credit card department, and stated that he hopes this gets resolved soon. What is the use of a priority banker if he cannot provide any help whatsoever. I have then send another mail to the ABSA ***** department (***), this came back with an automated mail to state that someone will phone me within 24 hours. Today is 04-03-2024, nobody has made contact with me yet. I have contacted the merchant from Dubai myself, and the transaction has been reversed for the amount of R7 925.28. There is a R538.72 difference that was not refunded. Up to now I have had no communication from ABSA. I feel this is a breach of their security measures and the customer is getting no feedback and are being done in with the difference of the refund. I need an answer as to how this transaction was authorised to even go through in the first place. When I contacted the bank, it was still uncleared, why did the bank go ahead and clear the transaction even when I am reporting it as *****? When will I be refunded for the difference. I am moving all my matters to another bank. This type of service is unacceptable.
