Do not buy electricity from the Nedbank app

Last Friday I bought electricity through the Nedbank app. It seems I accidentally entered the wrong meter number. When I received the token and tried to enter it on my Eskom meter it showed an error EEEEEEEEEEeeee. After reading the token sms again I saw the meter number is different than mine is. I immediately contacted Nedbank and was told that they can do nothing. They cant transfer the token number to my meter number even though it is not used. They said they also couldn't reverse or cancel the transaction. Surely this must have happened before? I think it is really sad that there is no way to fix this. They told me I must contact the municipality. However where I live is not municipal pre-paid meters as it falls directly under Eskom. I just wanted to warn other people to rather not use the Nedbank money app to buy electricity, because if you make any mistake they are not at all able to help you and the money would be lost, as is R200 in my case.
