Answer to question A, there are no other options.

Answer to question B, they will undoubtedly delete your account. And if you have a premium account like I do you will probably get a notice from PayPal that inbox.com has notified them that they are discontinuing my inbox.com premium account without explanation. My premium account with inbox.com is paid up to eighth of September 2017. I have yet to receive an explanation from inbox.com. I did save to my hard drive the receipt I received from inbox.com from 8 September 2016, I also saved my profile page from inbox.com to my hard drive showing that my account is valid until 8 September 2017 along with the notation on the profile page the account has been discontinued. Consider yourself fortunate that you have not spent any money for an e-mail account with inbox.com. Should I not get an explanation from inbox.com I will be filing a complaint with the FTC and provide them the documents I have saved. Should this happen I would like to be a fly on the wall when the gentleman wearing the three-piece JCPenney suits show up demanding answers.
