Impossible processes

I have been on the phone with FNB online since 8 this morning, got cut off about 3 times then the agents pc wasnt working and she couldnt transfer me so I had to be called back. Then I am told that I failed verification because I cannot remember the date that I opened my Identity account. your options are 0 to 2 years or 3 to 5 years. what happened to 2 to 3 years?????? All I want to do is to change the cell number for my OTP so that I can make a purchase. I sat on the phone for an hour and it still has not been changed, I have been a loyal customer for over 10 years and now I am ready to change my bank! Standard Bank and Absa Bank would never treat their customers this way.
