No, I've checked the spam/junk folders and contacted my service provider. Oh well. Thanks for the input though.

Assuming you are using a browser and not the iOS app, after going through what you have been through, the next things I would try are:
A. Updating your modem and or router’s firmware. (a router can block things too.) Reboot it/them as well, leaving it/them off for a while, so as to get a different IP address from your internet service provider.
B. Deleting your browser history and cookies and update it. Try a different (and updated) browser. (Or delete and re-install the browser.) Brave works OK. If you ARE using the iOS app, delete and re-install it.
C. Still no joy? Delete history and cookies again and try again from a friend’s WiFi. Once you have your login working you should be good, unless this is a country issue.
D. Truth Social function while running a VPN can fail if you land on a banned IP address..
Just my thoughts. Good luck!
