I have made an online purchase on etsy

I have made an online purchase on etsy.com and I paid it via google pay on 20 July 2023. Capitec charged me times 2 and not payment of R21 was processed to the third party. Why was I charged? Why did Capitec not payment for Google Pay? Mikhongelo Agent was busy assisting me and then she decided to drop my call. It happened with the previous agent also whose name i dont know. So when they cannot help you, the calls mysteriously drops.
