If so, watch out if you change your e-mail address. I just informed them of my new e-mail address recently and after a few days got an e-mail back stating that "due to security reasons" they couldn't accept instructions from my new e-mail address. So, I had to re-create my old e-mail address and having done so, sent them an e-mail from that address.
A few days later I received another e-mail from them, quoting a password which I should send to them in an e-mail to confirm that I wanted to change my e-mail address. This I did and a few days later I received another e-mail with a different password which I was supposed to quote in an e-mail (from my new e-mail address)to confirm that the new e-mail address belonged to me.
This I did and some time later I received an e-mail from them, at my new e-mail address, with another password, which I was asked to quote in an e-mail (from my old e-mail address) to confirm that I was the owner of both e-mail addresses.
Today, I received an e-mail, on my new e-mail address stating that "due to security reasons" they couldn't accept instructions from my new e-mail address.
I give up. How does the song go? There's a hole in my bucket dear Liza dear Liza...
