Impatient call centre agent, hung up the call

I contacted the call center to confirm how I could login into Online Banking without access to my banking app (since my smartphone crashed). The Agent confirmed that I would need to get a digital-token from the branch which was inconvenient given the urgency of my request. I then asked the agent to advise if there was any other way to transact perhaps using an OTP sent via SMS/email. The Agent responded in a rude and impatient time and then ended the phone call abruptly without resolving my query.
