has been down since Sunday

I have sent 3 e-mails to Pinterest on this subject. I use Chrome and have IE 9 but when I tried putting 10 on my machine Dell said noooo if it were capible it would auto update it Costing me $130 to fix it. When you come to sign in page, it flips about not letting you sign in. Then when I managed to get to my main page or boards page It has a very strange appearance. So I did all they recommended and no help whatsoever. I eventually received an email stating the issue was on their end and they apologized would try fixing it asap. I am still waiting for some resolution to the problem and of course somehow my prior complaints are missing. Very odd.! I just placed another e-mail and screen shot once again. This isn't working well..they change it all then its all messed up. Does anyone know more on this recent issure with their site.? 5/16/2013 Its been this way a week.
