Not satisfied

I recently joined capitec bank and I am really unsatisfied with their cellphone banking, specifically when it comes to prepaid options. When buying airtime/electricity, the customer is only given a few options when it comes 2 amounts one can choose and they do not give the customers a choice to enter their own. This morning I had 2 drive all the way 2 buy electricity because they didn't have the option for the amount I wanted, while I have cellphone banking and that was very inconvenient, time consuming and made me irate. The same applies for airtime, every time I want to buy it I have 2 buy more than I need because I cannot choose my own amount.
