i have a permanent suspension

so i woke up to a permanent ban on my xbox i’ve had only 2 strikes on my account and for some reason i never got any details on why i got banned. all i remember was i was playing rainbow six siege and this kid lost the match so he told me to end myself so then i told him to 1v1 me then i sent him very fake and random numbers and saying nice ip boi. i don’t think what i did was that bad it didn’t even match what a regular ip looks like and what am i gonna do with his ip if i had it anyway, i think my ban was unlawful and i would like some answers if i could do to get it back.
