HSBC Bank

Worst experience here ever. I came here to open a student bank account. The place tends to be very crowded with very seemly grumpy employees. I told the woman standing in the lobby that I was looking to open an account. I showed her my Bank Proof of Study from my university, a letter from my landlord as well as my passport with my student visa inside. She told me that all of my documents were fine and she put me in the massive queue to speak to the woman behind the desk to open a bank account.
The next available appointment was in 3 weeks from that time! I was shocked and annoyed, but I decided to schedule anyways since I heard HSBC was a good bank.
However their customer service makes me think otherwise. Alas, it was 3 weeks later, and I went in today to finally open my account. I spoke to the same woman who helped me 3 weeks ago. She treated me and spoke to me like I was a criminal and I felt like I wasn’t «allowed» to be a privileged HSBC bank cardholder. She told me my university’s Bank Proof of Study was not legitimate because my Dean of Students signature was digitally printed (as if the dean of students would actually sit around hand signing 300 bank letters to foreign students all day). The 2-​color stamp and the librarian’s signature on it apparently was good enough 3 weeks ago, but not good enough today. Also, my passport/​visa, a bill from my university and my landlord’s letter was not good enough to even open a basic account.
Fair enough if you have valid reasons to accept my letter, but approving me, make me wait 3 weeks to only treat me like a convict and turn me away.
«Would you like to schedule another appointment?»
Are you kidding me? NO. Bye!
