Blue Label and Capitec Bank

My name is Leo Moshe. My phone number is ********** 835. Today I bought airtime 2 gig data from my banking app. I initially called and MTN and was referred to my bank. The shock I got is not on. All I heard was an agent wanting me to understand that I could be refunded after 24 hours as it was a blue label error. They don't sell airtime, it comes from blue label. I tried to explain that their relationship is not supposed to affect me as I paid for a service and was entitled to it. No acknowledgement from the lady agent that was on the phone, she just blame shifting to blue label. I really need you to please assist me as R260 is a lot of money
