GM Response Feedback - Feels like my message was responded to, but not read

I understand the use of pre-written responses, and don't really fault GMs for them: if you have to say roughly the same thing 100 times a day it makes sense to have something you can copy and paste. My main concern is about the last report I had, about a player spamming PVP quick chat in Crystalline Conflict. I had matched with a person that was spamming quick chat, so after the match I blacklisted them. I would have left it at that, but then I queued again and got them on my team, and they did it again. It appears that blacklisting doesn't stop you from seeing quick chat. So I messaged a GM about the spam, and mentioned that I had blacklisted them and it didn't work.

Their response to me was the normal response for having an issue like that: Thanks for reaching out, we'll look into it, and blacklist them in the meantime. Aside from the issue that (as far as I'm aware) you can't blacklist someone during an instance, in this particular case I'd already mentioned in my original message that I had already blacklisted the person and it had not worked.

Now, I completely understand boilerplate responses when they make sense. The issue is that in my message I pointed out that I had attempted blacklisting (and that it hadn't worked,) and the response was "you should blacklist them." It makes it seem like they didn't really read my initial issue at all. What's worse is that I replied to the ticket explaining that I'd already mentioned the blacklist not working, and they responded saying: "We understand that you are contacting us to provide additional information regarding a previous report that was submitted, and we will be happy to update all on-going investigations. The information you have provided will be added and considered while we review your report thoroughly. Should additional information be required, we will contact you as soon as possible."

My response had no new information, since I was just reiterating what I'd mentioned in my first message: I had already blacklisted someone, and that blacklisting would never fix the issue with quick chat spam since that's something that's not stopped by blacklisting. Between the initial response (that I've seen too many times over the years,) and this new response, it makes it seem like my issue wasn't actually reviewed at all.

I'm sorry if this is the wrong forum for this. I've had plenty of GM ticket interactions over the last year or two, and I'm mostly pretty happy with how fast they get back to me. It's hard to tell if something gets done (like when I report people sending out random phishing tells,) which is why I felt the need to leave this feedback in the first place. I'm still pretty satisfied, but just wanted to point out my issue since with pretty much anything there's room for improvement, but it's hard to improve if you don't know what issues people are having.
