False advertising and inferior services offered

Standard bank advertising that you can purchase electricity using the cellphone or Internet banking. For the past 2 weeks I have not been able to buy electricity using any standard bank application. I have contacted the bank who said they are aware of the issue and are busy resolving it with the city of Cape Town. 3rd week now and still it doesn't work. Such as inconvenience as I can only purchase electricity using cash in store. So must first go to an ATM then to a shop whereas with all competitor banks you simply purchase electricity on your phone or PC without leaving the house. Really pathetic service I don't know why I haven't changed banks by now as they always offer inferior services to other banks in SA.
