Toto's Pizza House

Could you please help me. I created the page Toto's Pizza House and then moved it to User:Pestbuda\Toto's Pizza House, and on realising I used the wrong slash moved it to User:Pestbuda/Toto's Pizza House. I've tried to move it to Toto's Pizza House and have been told I cannot. Could you please help me move it to just Toto's Pizza House. There are a lot of things I need to put on it but if it can be put on WP proper I think it will be OK. I've also put links, which was a silly thing for me to do before creating the article.

If you could help me I'd be very appreciative, or if you cannot suggest another administrator familiar with this problem, which must have occurred before. Thank you.
