Huge complaint!!!!!!

I have wasted an hour on the phone trying to fix the internet access to my British Airways/ABSA credit card. I have been asked a series of different security questions 4 times. Each time I have been told I have failed so they cannot unblock my account. Now I have been told I must go to an ABSA branch. Absolute madness. I have no idea if they are confusing me with one of my sons or what their story is. I am a 79 year old pensioner and I really don't need this ******* in my life. I have never had an experience like this with any other bank
