Should I be upset if my supposedly "friends" for 9 month does not really know my name?

So I have these 2 twin friends and for like 5 months, I never heard my name being said, I mentioned my name a couple of times to make it not awkward. One tried to spell my name through text once but used my discord name which is the actual pronunciation of my name but the actual spelling is different, which I wonder if he even notice the multiple times I paid him on venmo (atleast 20 times) that has the actual spelling of my name (so I did told him if he noticed my venmo name, this is 5 months in).

Ex: a vietnamese name spelled “Anh” would be pronounced like /un/ and my name is 1 syllable so it’s not an extremely hard name.

I finally called him out jokingly yesterday (9 months of hanging out) after he butchered my name lol (which I think was the first time he tried to say it 0_0) and his twin who hangs out with me almost every time wasn’t sure either but he payed attention to someone who said my name earlier of yesterday and remembered. Overall just a funny story for me, although I feel a little awkward that I had to mention it explicitly but better than years later haha. I was wondering if I should be mad and my other friends practically implied that I need to respect myself more and it is not okay. I like to see it as they don’t intentionally want to be rude but ended up doing so and it might be relating to their ADHD to some extent…
