I would like to update my username to be indymassageco

I'm sorry, but indymassageco is no longer available. I think you have accidentally registered this account with an incorrect email. You missed the letter L in gmail.com. 

We can free this up for you and use it for your account, but since we cannot change the username through Paypal, the subscription needs to be canceled first. We can refund the payment for you as well. 

To cancel, go to your billing page and click the free plan.

You will have to re-upgrade once the username is changed.
