Tried to access old account it instead made new one :(

[curuxz2]

First time using the forum in years and I went through the ubuntu one thing as that was the only login option. But instead of logging into my account curuxz it made a new curuxz2.

I would like to delete all the posts from curuxz and remove the account from the forum. Then remove curuxz2.

Would someone be able to help me please?
