I've paid for my account but it's not showing up

My account was charged for a new month's subscription yesterday. Then this morning, I get an email telling me that my account is full, out of space, no longer syncing. I went to my account and logged in, and it says I need to upgrade, that I'm only a Basic user! But, I am a PLUS user and have been for many years! I'm not going to pay to upgrade my account to a level I'm already at - especially when they just billed me yesterday! The payment was successfully processed, I checked. So, there is no reason for this.

NONE of this makes ANY sense to me whatsoever:
- My bank account processed the payment for my subscription successfully.
- I pay for my subscription through Google Play - which shows me as an active Plus member, with my next payment being due in April.
- The email I received was telling me to upgrade to the next level of 3 TB. But, 3 TB is NOT the next level up from Basic - 2 TB is! So, that makes it seem as if I'm already at 2 TB...?
- When I logged into my account, it said I was using a little under 6 GB, and that I was full, out of space, no longer syncing - meaning I'm in a Basic account.

Since the account is showing me as Basic, I'm unable to contact anyone in Customer Support for help - no phone, no chat, no email. Apparently, that is only for "paid" customers - WHICH I AM!!

I need help with this. I need to know if any Dropbox employees monitor these boards and might see this...???

I have MANY important documents saved in my cloud, so I need this working correctly again!

Any help would be extremely appreciated. Please.

Thank you,
