The private key you created with PuTTY may require a passphrase. That may
be what you're seeing.
Or, their end may not be correctly finding the public key for you. If it's
not, then it may be reverting to password or keyboard-interactive
authentication.
I believe PuTTY can run with some debugging turned on. This will give you
some information about what authentication methods it is finding,
allowing, tying, failing, etc.

This sounds seriously like their SSH daemon is not set up properly. Are
THEY able to SSH to their server? Are they able to do so and log in with
your username?
It's also possible that they succeed from inside their firewall, but when
you attempt to come in from outside the firewall, the firewall (or router)
is intercepting the SSH connection. They would need to configure the
firewall/router to forward a port 22 (default for SSH) connection to the
appropriate internal machine.
Are THEY able to connect in from the Internet at large (outside their
office)?

It sounds to me like it is on THEIR end.
You might want to try Anzio Lite, our SSH client, available from the
website below.
