Does not come back with feedback on my problem

Once again, Absa's service sucks. Firstly on the 8th of March 2016, I send a e-mail to find out why I can not buy pre-paid electricity online. The response I got was that I can not buy electricity from the APP. I then rep**** that my query was not about the APP but online. This response come on the 12th of March 2016 4 days after my e-mail. Because I had to wait so long, I phoned. The person I spoke to then told me I can only buy pre-paid electricity from cell phone banking.I tried to buy electricity from the cell phone banking as the person I spoke to said that I am registered for cell phone banking as well. I could not buy pre-electricity as it got stuck on the last page of trying to buy. I then phoned Absa again, and this time the person was not at all helpful and he told me that I am not registered for call phone banking. I guess he just did not know what else to tell me, or he just did not want to help me. I responded to the e-mail on I got on the 14/03/16 and told them my problem again. Catherine responded to my mail on the same day :) and I rep****, but till today a week later I still have no response and I still don't know why I can not buy pre-paid electricity.
