I don't remember the specifics because it was a while ago. But there was a problem with my internet. So I called my provider and sat on hold for over half an hour before getting through to someone with such a thick accent, I had trouble understanding fully what they were saying.
I'm generally pretty good with accents, having a broad experience with university professors and friends, so I think an amount of my frustration was with myself for having difficulty with understanding her.
We talked back and forth, me trying to explain my problem and her trying to say that wasn’t a problem. I got steadily more frustrated because I'd been without internet for over a week, but due to being busy at work and then tired in the evenings, I was using my first day off in over a week to fix my issue to enjoy Netflix and the likes. And also not have my family jump down my throat because we were on a family plan and shared 8GB of mobile data at the time. I wanted my Wi-Fi back.
Finally she determined that we had a problem, and I had been pretty snippy. Normally I'm happy and cheerful when dealing with customer service, it’s not their fault my thing is broken and they don't deserve a bad attitude for trying to help. They're not paid enough for that. But it had been a very long week, and I had only scraps of patience. I didnt swear or anything like that, but I was quite short with her and it was clear I wasn't in a good mood.
I felt pretty bad when she was thanking me for not swearing at her and calling her bad names, or yelling at her. She kept repeating that to me as she transferred me to a different department. I thanked her for her help in the most apologetic tone I could muster, and steeled myself to not do the same to the tech hopefully about to reunite me with my internet.
