Terrible phone customer services experiences

Today (10/16/19) at around 1:20pm, I contacted Dell support over the phone regarding a problem of my newly purchased monitor U3417W. The lady who picked up my phone call was truly inpatient while I was trying to give her the detailed information she needs (service number and some of my personal information). I was asked to give her my full name, but somehow she kept asking for my real full name - which I already gave her. I do not have an English first name so I am not sure why she kept saying she needs my real name before helping me on my monitor. And then she went mad and started to yell at me. I hanged up the phone right away after she started yelling and I made another phone call to complain about it but nobody on your side actually cared.

I have been a big fan of Dell products for many years. I truly love your products. My laptops, monitors, and even keyboards are all Dell products (let me know if you want to see all my service tags of them like that lady did and I would be glad to provide). But I never knew I may need to change into an English first name to make purchases from your company in order to get proper customer services and I am the one who should make your customer service representatives happy when asking for help. 

I don't really know how you train your representatives. I don't really want to accuse her of racism right now without knowing what was exactly in her mind (but I think many other people will). Let's just think she was just having a bad attitudes or maybe a bad day. But I think it is already enough to say some of your representatives are not professional enough in losing temper to your customers. Is this the way you do business?

For so many years, I never had any issues with Dell products and this is actually the first time I contact your customer service. In the end, this is what I've got. I probably will never buy any of your products again.
