Registration form validation

[deepcoding]

Hey,

I got a new problem, when I try to register and I use a false telephone number or an email address
which is already in use, I get the error but no form.
I see the error, then I am redirected to the cart, at the billing address is see my fields´, so the account was created although
there was an error and I get no email with activation link.
Can someone help me?

Thanks
