Two Hours Wasted - Thanks, FNB

I have wasted two hours this morning with First National Bank trying to do a very simple thing - just to change a telephone number so that it can receive otps. First mistake was going to FNB's My Service Suite on the FNB app (never have I seen such an inefficient and antiquated system) - gave me totally bum information which meant that I spent an hour looking for something on the FNB app which wasn't there. Turns out that it could only be accessed via my bank account which wasn't made clear. Then the instructions given were totally wrong - so another hour wasted trying to find a human to speak to. So two hours down the line and I am no further forward than I was - other than I am totally frustrated and very ready to tell FNB what they can do with their banking "system". A total joke.
