I want my money back!!!!!

I recently took a contract with Telkom, I ran out of bundles and used my Capitec bank to buy the airtime and subsequently data. This all was allowed and received confirmations of the transaction and amounts now I am being told that the airtime doesn’t appear on my side and even though I have bought the bundles I still need to pay for the service because I am not allowed to buy for myself. I am frustrated because I want my money back since I’ll have to now pay money twice
