Hugely frustrating process

Their service has been shocking. It takes ages to get my monthly token for electricity. When I want to top up my account with my credit card, it takes up to 30 minutes for the transaction to reflect on their system although my bank sends me an immediate confirmation. Any other online business processes my payment immediately. In my pure frustration I decided to investigate other options. Low and behold, I can buy electricity directly from my bank. It takes 30 seconds! Why would I want to give my myself so much pain with these guys? Now they keep sending me sms’ asking that they would like to retain me as a valued client. You can’t respond to the sms but you have to go to their website with the link provided and lodge a complaint filling in multiple sections. Far too much effort.
