Can't change page name

Facebook takes a while before it accepts name changes. How long? I really don't know. But they do not grant them immediately. There does seem to be a delay in the process, most likely to assure that people don't like one sort of page and then they're trolled and it turns out it's a rather different kind of page entirely.

Yes, but they say that the answer will be given in 3 days, some friends have an answer in couple hours, except Facebook need more informacion, but then they replys, im still ignored or something.

UPDATE: when i send a request after that few hours į cant send it again because this option stoped until fb reacts to request. After few hours or ~ a day į again can send new requests, so fb reacts but nothing happens, no accept no denied, supports not helping. Something wrong, what is it??

I had the same issue a little while ago. Does your page have locations turned on by any chance? I was testing locations for a bit, and I was only able to change the page's name after I turned that feature off. I hope this helps! I know how frustrating it can be.
