Money gone but no Electricity

I have on 3 separate occasions used my internet banking to purchase electricity to the value of R300.00 and I did not receive the voucher number and to date I did not get the electricity, when i look on my statements it does not reflect but the money is gone??? How did i just get ****** by my own bank?? I dont think that this is fair as I have been banking with this bank for more than 10 years. I have fees going off these accounts continuously that I am not even aware of. overdraft fee but I dont have a overdraft??? what is this about??? <br> <br> Please help me or must I change my account to another leading bank in SA
