Help. These are not my accounts

I found that my profile was linked with different accounts. These '7M’s are not my account. I want them to be unlinked with my account. And, I want to change my esports profile name from 7M to ‘전래동화’. I mailed that I just want my esports profile name changed from 7M into ‘전래동화’, but then these accounts are linked with my account. I don’t know why my esports profile was named 7M. I haven’t touched anything with my esports profile in royaleapi. Please consider help :pray:
