This is likely a recurring theme, but telephone support people. I had an unknown transaction on a credit card so I reported it via their app, and they canceled that card and are sending me a new one. So far, kudos to them for making it so easy.
I then received an email saying I could get my new card number through the app, which I need in order to update recurring transactions. After exploring every single button in that app I couldn't find that number anywhere. So, time to call tech support. Typical. Wading through myriad options before I could talk to a human. The inevitable long hold time.
Why the heck aren't these people trained to speak intelligibly? Mumble, mumble, mumble. "Excuse me, could you repeat that please?" Identical mumble, mumble, mumble. "Could you speak more slowly, please?" Identical mumble, mumble, mumble. "Perhaps you could rephrase that?" "SIGH! [on their end]"
THEN, when that first person couldn't figure it out they transferred me to another rep in the app tech support department (wasn't that the menu item I chose in the first place?). We start all over again with name, security information, and they have no clue what I'm calling about. Then THAT person has an incredibly thick accent and speaks at a machine-gun pace. Finally, I just told them 30 minutes was enough, I was done, goodbye. I get my new card tomorrow anyway; I just thought it would be an easy fix.
