Paid for new 12 month Plan Today, but Cannot access Email Account. Help ASAP. This is a repeat issue

Hi Mailbox team. I am sorry to have to leave a comment again here on the user forum like last month, but I require access to my email account ASAP, today please. (Paid for my new annual membership today but my email account not working and the contract status in account settings incorrect, i.e. not up to date.)**

I am currently blocked from using my email account here. My drive seems to be ok, I have access to it but my mailbox email account is not available to me. It is urgent as I have emails to respond to today.

Please can you fix this problem for me today, 31st August. Thank you.
