Electricity Token used - Bad Service

I am taking my account away from FNB and I will tell everyone what my experience has been with FNB. Being sent from pillar to post all day. I bought electricity early this morning. Voucher numbers were used on 16 March 2015. I want my money back and FNB says NO. FNB passes the buck to the supplier and the supplier passes the buck to FNB and the cycle goes. I thought this bank and its transactions are free from blunder. I was wrong. Even Capitec bank never gave me this problem. Nedbank is calling me every month asking for my services. This time around I will say yes.
