Bad service

I went to the bank on the 19th at 14h15, It wasn't busy there only one person was working at the entrance, a lady who was on a phone assisting a client, an old lady who was expecting money from overseas from what I could overhear. I was the only one at the door, then another lady joined me, still we were not helped, other staff had to be called, 2 went behind the counters one came towards us her name was Cecilia she asked what help I needed I said I need a stamped confirmation letter for employment, she insisted that I should get one from the app and informed me that it's the same thing even though I specifically asked her for a stamped one, then she said the other lady behind the counter will help me, she went outside towards the ATM's I then went to the counter and they told me they are still busy with treasury, then I was instructed to wait on the couches again, the lady that was initially on the call helping the while old woman who was with someone else then asked for my ID, asked for 2 letters as instructed by the employer, she was also complaining that it's not allowed anymore to get a stamped letter I should retrieve it from an app the unstamped letter. Their service was bad.
