Transaction not yet processed

I made payment using my credit card to Avis for renting a car on 17 February 2022 and money was withdrawn from my account. Days later I returned the car and waited for my refund, which I did not receive. When I check my credit card statement it reads"transactions not yet processed" I'm confused because Avis was not going to give me the car without payment and I received an sms notification of R1500 deducted on my account. Capitec it seems that my money is hanging somewhere, can you please release it back to my account.
