App Change Electricity Meter Number but not the amount. Bought Electricity for wrong person.

Almost bought R700 electricity for a friend instead of myself. Clicked back to switch to my meter number and the app only changed the amount to R700. So I bought my friend R700 electricity. There is no way to transfer or refund.

This is a ridiculous design prone to user errors. Please fire the person who designed the electricity buying feature for the app.

This feature should have a profile for each meter number saved with a name. The user can visually identify who they are purchasing for with one glance. Who memorizes meter numbers anyway? The amount should easily be modified instead of having to incorrectly re-enter the meter number (which you entered correctly once already) every time you want to buy for a new amount.
