When a mistake is made during phone registration, let people delete it and start over.
I tried to register and my phone was out of service, I was asked to give my phone number, and as soon as I gave it, there was a text sent I could not retrieve, and it wouldn't let me start over. I tried to delete the account months ago and just checked back and it's still not deleted. So I still can't get started. you should change this so you get more business and customers aren't forced to use a different service.
