Crypto/Blockchain

Anyone on here any experience, and including with e-mail issues?

Have to ideally, for security, use 2FA log in to my bitcoin wallets.

This requires for firstly, responding to their e-mail to authorise log in, and then for responding to an sms code to a mobile.

Have used this for almost a year but, from yesterday, their e-mails are not received!

I'm getting other mail as normal, so the question is why a problem with Blockchain?

'Talking' to them is useless, as they never grasp the issues, and their responses may just as well be to someone else!

Their last word is that I can't change the settings without logging in! Well that's a great help!
