I recently received an account statement by post from a financial institution. There was a slight spelling mistake in my email id in the statement i.e email@example.com was written as firstname.lastname@example.org. I called the toll free customer service number and was told to courier a letter with my signature and the correct email id. I was told that this was the only way out since they needed to tally my signature with the application form.
Suddenly, I thought of sending an email to the customer service and accordingly did that. Within two hours, I received an email from them saying that they have updated my correct email address in their records.. I had just asked them to correct the email address which was promptly done without asking for my signature. But then why was I told to send a signed letter to their postal address while speaking over the phone??
