reverting back to wordpress.com site

i had a beautiful site on wordpress.com, but decided i needed some plugins and needed ww.wp.xz.cn. i set up a hosted site at godaddy. then exported my wp.com site, changed the nameservers at godaddy, then imported the site into the new wp.org login. now my site is a disaster!! can i revert back to the old site?? i changed the nameservers back to NS1.WORDPRESS.COM (etc). it still looks awful though. not sure if the nameservers have switched yet, as its only been 20 min. i don’t know if there are other steps i need to take or if its even possible to switch back. panicking big time! any help would be great. thank you so much
