I just sent 4 pics, all less than 1MB in size, to my energy supplier.

Now I can't log into mail, and the messages say my account might be locked, and that I should try to change my password as it may be compromised:

Your Virgin Media Mail account is currently unavailable

This is either because your Virgin Media Mail account is locked, or because you don’t have an active account with us anymore ......

However, when I try to do that, I get:

Oops, we've ran into a problem.
Wait a minute and try again. If this doesn't work, please come back later. (Code: DEF01)

Any ideas?  Who knew that sending a mail to an energy supplier could be so damaging?! 😉

Thanks
