Creating a looking for group post!!! DO NOT GET THIS FORUM LOCKED

Hello, So I am extremely angry with this now so back in 2020 I spent a month talking with microsoft about this and they ended up just stop talking with me so i still havent got a fix for this; i have 3 accounts on my xbox The main one I played for a couple years I stopped playing on it in 2021 in 2020 i tried to create a group post on all 3 accounts non of which work. So in 2021 I ended up moving to my second account (third account is my moms) I just recently today got the idea of creating a group post. So i ended up trying and well you know how that went (There was a problem posting your looking for group) So I ended up creating this thread because im extremely angry now. Something to note is last week i ended up changing up the info on my xbox and microsoft accounts, what i mean by that was apparently when a friend created them for me the birth dates were completely wrong, We always use to have the issue that i was unable to do something on my xbox because it was a child account well I ended up changing the dates because they were wrong and we finally got that fixed! So when i tried to create the group post today i thought that was the issue, WRONG!!! So I am making this thread because I have actually had enough of this and the fact that an employee at microsoft couldnt fix the problem for over a month he ended up just saying im sorry but we cant think of anything just get a new xbox, I was so shocked that a microsoft employee had said that to me the day he did it blew me away, because that was completely unprofessional, Im not trying to accuse anyone, all im saying is im extremely frustrated that microsoft couldnt fix it in 2020, also keep in mind i was reading threads and i saw 2 other threads on this 1 of which ended up getting locked because apparently someone asked another question which they didnt thats why i stated in the title dont get this forum locked. Now on the other thread this kid ended up saying in his thread that how he fixed it was it magically got fixed after a week of waiting, thats when i about lost my [mod removed] And i have been trying to solve this problem ever since 2019 (also dont ask me what im playing on Im playing on the xbox one s (it looks white) Now I have had enough also in 2020 in that month they ended up telling me to try things like resetting the network, switching to a different network, moving to a new location, doing a power cycle or whatever any cycles that involve shutting down or restarting or unplugging the xbox, they also had me check every single setting that i have used on the xbox non of which were the problem, they also told me to try completely resetting to factory, (I did that) they also had me try it on different accounts, they also tried having me do it on a friends xbox with the same account (it didnt work either) so there final answer as you know was get a new xbox. So is there an absolute legendary genius who can help me out with this because im sick and tired of this!
