Absa poor Service

I have app**** for a credit limit increase it was granted . Then requested an interest rate review as the interest i was being charged is too high and my interest rate was never reviewed when i was moved from virgin money to absa creit card. I call back in June\July to request the review i was told i would receive feedback in 24 to 48 hrs. I did not receive anything. Called again in August i was told the same but never received the feedback. I call again today 07\10\2021 and there is no feedback. If this is not resolved within 5 days im moving to a different bank
