Unable to Upgrade?

hi, thanks for trying to help.

I spoke with 3 reps over the course of the last few days on the chat, I do not know that rep name. It was the last rep who I had on chat for almost 2 hours yesterday who told me Dropbox was aware of this ongoing issue. I don't know who that was.  One of the reps seems to have opened a ticket, but she keeps telling me it's paypal. I can't even get to the checkout screen! I had others try logging in to upgrade on my account, using different networks & different computers, they cannot access this page either. You see CHECKOUT but it spins and says "something went wrong, contact customer service" I just tried again, day 4...not working. In the meantime, I cannot share my files & this is my business.  I cannot opena  ticket, because when I go to customer service & try to create an email, the only option I get is REFUND/CANCEL.  I even tried making up stuff to get this to submit, but you can't submit anything.  It's greyed out with an error message.  My computer tech tried this for me as well and got the same error..he's in a different state. Beyond frustrated. thanks for any advice you can give me. I just wish I could get someone to help me.  thank you  - and regarding my previous payment page, yes I can see my last few payments no problem.
