I found that there is a new plan promotion:
free domain and free for 3 month if I sign a one year contract

Actually I have a domain on your server and also a payment plan (PROFI) month to month, the space is 1 G because I signed almost one year ago.(month to month plan).

1.Can I change my old PROFI plan to your plan(new PROFI) and
Get a free domain
Get 3 month free(1 year contract)
Get more space and bandwidth(3000 Mb)

* I paid for my old domain name, so I want to get a new free domain name with this new plan(PROFI).

Thanks a lot
