who else is having problems doing anything with their shop on ebay?

I can not change item numbers, edit anything. I can not change from one page to another without being told that to sign in yet again. Then it sends me through to the beginning again.  I have tried all help desk solutions and frankly at my wits end. 

I can not answer a message from a buyer unless I try to send it multiple times each time the original message wont send so have to write again.

I contacted ebay about the problem three days ago and told it was being is fixed. It is not. I can not relist items either it just scrolls endlessly.
