Very unhappy customer

On the 15th Feb I bought electricity vouchers for R 1 000 via FNB app in the morning and still to date haven't received my token #. I called to report the issue and was advised that they were experiencing delays. I made them aware of my electricity being low and could go off at any time and was advised to go buy from the supermarkets. I went and acquired for R 100 to buy time. The commitment I received was that will receive the token # before the end of the day on Sunday. That did not happen as the next day I had to incur additional cost as I acquired R 500 vouchers as it is a costly exercise to buy in small amounts. Today is Tuesday and still to date haven't received the token #. I called yesterday and was sent from pillar to post eventually I gave up. I am so fed up with FNB in all aspects as last time I reported an Ebucks issue which was never resolved and just had to live with it. Now my R 1 000 is also down the drain. Imagine the inconvenience caused and the driving around to buy this electricity from the supermarkets. I am so disappointed with this bank and all I can say is I give up.
