Debited twice, there is nothing capitec can help me with

I have been debited twice for my credit card in one day. I went to the branch on west street. They can see the money leaving my main account but its not reflecting on the credit card. The lady who was helping me simply told me there is nothing she can do if the money doesn't reflect although it left my account they can not help me. I must come back to the branch another day.

Tell me how do i continue banking with a bank that doesnt care for customer service?

Who is liable to pay charges for these duplications?

What happend to my money?

Who will pay my funeral cover premium if the money has been debit twice and there is nothing left for the funeral cover?
